Fix to tc-scripts.min.js to allow for custom page templates

When plugins or individuals create their own page templates for whatever purpose, your tc-scripts.js/.min.js generates a javascript error when no navbar is found on the page. The issue is this.$_nav_collapse is being defined as an empty object when there’s no header, and then later you reference properties of that empty object without checking if it’s empty first.

Please change this:

this.$_nav_collapse=b.$_tcHeader.length>0?b.$_tcHeader.find(".navbar-wrapper .nav-collapse"):{},this.$_nav=this.$_nav_collapse.length?this.$_nav_collapse.find(".nav"):{},this._has_dd_to_move()&&(this.$_navbar_wrapper=this.$_nav_collapse.closest(".navbar-wrapper"),this.$_nav=this.$_nav_collapse.find(".nav"),this.$_head=a("head"),this._dyn_style_id="tc-dropdown-dyn-style",this._prop=b.$_body.hasClass("rtl")?"right":"left",this.dropdownPlaceEventListener(),this._place_dropdowns())},dropdownPlaceEventListener:function(){var a=this,c="tc-resize sn-open sn-close tc-sticky-enabled tc-place-dropdowns";b.$_body.on(c,function(b){a.dropdownPlaceEventHandler(b,"resize")})},dropdownPlaceEventHandler:function(a,b){var c=this;switch(b){case"resize":setTimeout(function(){c._place_dropdowns()},250)}},_place_dropdowns:function(){var a=this._get_dd_to_move();a.length&&(this._staging(),this._move_dropdown(a),this._write_dyn_style(),this._unstaging())},_has_dd_to_move:function(){return this.$_nav_collapse.length<1?!1:this.$_nav.length&&this.$_nav.find(this._dd_first_selector)<1?!1:!0},_get_dd_to_move:function(){return"absolute"==this.$_nav_collapse.css("position")?{}:this.$_nav.is(":visible")?this.$_nav.find(this._dd_first_selector):{}},

to this:

this.$_nav_collapse=b.$_tcHeader.length>0?b.$_tcHeader.find(".navbar-wrapper .nav-collapse"):{},this.$_nav=this.$_nav_collapse.length?this.$_nav_collapse.find(".nav"):{},this._has_dd_to_move()&&(this.$_navbar_wrapper=this.$_nav_collapse.length>0?this.$_nav_collapse.closest(".navbar-wrapper"):jQuery('body'),this.$_nav=this.$_nav_collapse.length>0?this.$_nav_collapse.find(".nav"):jQuery('body'),this.$_head=a("head"),this._dyn_style_id="tc-dropdown-dyn-style",this._prop=b.$_body.hasClass("rtl")?"right":"left",this.dropdownPlaceEventListener(),this._place_dropdowns())},dropdownPlaceEventListener:function(){var a=this,c="tc-resize sn-open sn-close tc-sticky-enabled tc-place-dropdowns";b.$_body.on(c,function(b){a.dropdownPlaceEventHandler(b,"resize")})},dropdownPlaceEventHandler:function(a,b){var c=this;switch(b){case"resize":setTimeout(function(){c._place_dropdowns()},250)}},_place_dropdowns:function(){var a=this._get_dd_to_move();a.length&&(this._staging(),this._move_dropdown(a),this._write_dyn_style(),this._unstaging())},_has_dd_to_move:function(){return this.$_nav_collapse.length<1?!1:this.$_nav.length&&this.$_nav.find(this._dd_first_selector)<1?!1:!0},_get_dd_to_move:function(){if(this.$_nav_collapse.length===undefined)return{};return"absolute"==this.$_nav_collapse.css("position")?{}:this.$_nav.is(":visible")?this.$_nav.find(this._dd_first_selector):{}},

Thank you.
