Timing of 'chosen:showing_dropdown' fixed
Timing of 'chosen:showing_dropdown' fixed

Currently the event is triggered before dropdown LI's
are created. This commit corrects it by moving the
trigger event at end of method. A JSFIDDLE was created
to demonstrate the issue.

By moving the event it enables developers to add
whatever additional code or styling to the dropdown
menu options such as images.
