If 'search-enabled' attribute is missing, use value, defined in 'uiSelectConfig.searchEnabled' instead of hard-coded 'true'
Changed the choices.tpl to fix bug with IE groups

Modified all 3 of the choices.tpl.html to fix a bug that was not
allowing IE to render group names. Instead of using {{}} for the name I
switched it to ng-bind syntax.
Added tests to check behaviour of searchEnabled option of default config object.
