ENYO-3928: Make unchecking the alwaysLooksFocused checkbox take action.

Issue
-------
Unchecking the 'alwaysLooksFocused' checkbox does not cause the input fields to have focus removed.

Fix
----
We trigger the blur event on the input fields if the `alwaysLooksFocused` checkbox is unchecked. Additionally, the `onyx.InputDecorator` around the checkbox has been removed.
