Style Background Transparent Not removed on Destroy

[Johnferguson1440]

When mentionsInput is initialized it adds the style background transparent. Found that when you destroy the mentionsInput the style remains on the element. I would expect when destroy is called that everything that was added would be removed. Currently just manually removing the background color when calling destroy. Possible solution to add to the destroy method is to set the background for the input to empty string to prevent unwanted css applied.

This fixes it for me if i update the js file
MentionsInput.prototype.destroy = function() {
this.input.areacomplete("destroy");
this.input.off("." + namespace).attr('name', this.hidden.attr('name'));
this.input.css('backgroundColor', '');
return this.container.replaceWith(this.input);
};
