fixed typo

Another typo
No longer rely on the DOM to deselect last selection

When choosing an option in a single select, we need to update the
array of options to deselect any previously selected options.
result_single_selected is no longer used
Move some repeated logic into abstract chosen
Make sure selected items are cleared after resetting Chosen single
Remove superfluous variable update
Docs should state that we (maintainers) will reopen issues.
Add support for a create option

Shows if there is no exact match
Fix width when the select is not yet hidden

I cleaned up the code from:
