Special characters in node titles are not rendered correctly

That is not an issue caused by Entityconnect.
It happend in Entity Reference module in class "EntityReference_SelectionHandler_Generic" due to check_plain in label line 173.
$options[$bundle][$entity_id] = check_plain($this->getLabel($entity));

Remove check_plain() should be safe because form_select_options() already does a check_plain.

Attached patch apply the above suggestion.

Please, just apply the patch and submit new version. It's simply...

Test failed because need to delete same functions from tests: entityreference.handlers.test

// Row 100
$node_labels[$key] = check_plain($node->title);

// Row 247
$user_labels[$key] = check_plain($user->name);

// Row 405
$comment_labels[$key] = check_plain($comment->subject);

// Row 579
$node_labels[$key] = check_plain($node->title);

I re applied the patch to HEAD and fixed the tests as suggested by mbaev in #3

Forgot to trigger the test bot.

Thank you, @esolitos!
