Supporting CollectionType

[thisismzm]

It has an issue when I use CollectionType to generate collection of Select2Entity instead of using multiple=true.
For CollectionType you should get $form->get($request->get('field_name'))->getConfig()->getOptions()['entry_options'] at the following line:

select2entity-bundle/Service/AutocompleteService.php

Line 43 in 66f5154

$fieldOptions = $form->get($request->get('field_name'))->getConfig()->getOptions();

On select2entity.js you should fix generating field_name too. The following pull request solved this: #119
