fix(selectize): show placeholder when search disabled

Previously when searchEnabled was set to false, the placeholder would
also be hidden on the selectize theme.

This fix sets the search input to disabled rather then hidden when the
searchEnabled attribute is set to false.

Fixes angular-ui#949 and angular-ui#691
