ZF-9619: Custom Translate Adapters don't work in 1.10.3
After revision 21661, custom Translate Adapters are not being executed. Instead, a notice like: Notice: The language 'en' has to be added before it can be used. in /Path/to/library/Zend/Translate/Adapter.php on line 394 is displayed. Reverting changes from the revision fixes the bug, and has the Adapter working as before.
