Changing email format to HTML breaks password reset

The SS plugin adds a filter to change the default email type to text/html. This has effectively broken the password reset functionality. I confirmed it’s SS by disabling the plugin, and password reset works as expected.

Rather than having the plugin change the global default, it seems a better practice to add the filter before SS makes a call to wp_mail, then call remove_filter to un-do it afterwards.
