Booking form field not labeled

There is a slight mistake in the markup of the booking form so that the Booking Comment field will be flagged in accessibility audits as not properly labeled. The <label> is there, but the associated <textarea> does not have an ID.

In this file: events-manager/templates/forms/bookingform/booking-fields.php, line 27: add “id=’booking_comment'” to the <textarea> field.
