Fix priorities when loading language files
Fix priorities when loading language files

Labels defined in the Extension framework (for example after exporting customizations from Studio and loading the module with Module Loader on another instance) can not be changed with Studio.
Steps to reproduce:
- Add a field to Calls with Studio
- Export customizations
- Load the generated module in another instance
- Go to Studio and change the label of that field.
- The change is not taken into account.

The changes is properly saved in custom/modules/Calls/language/en_us.php
But it is overriden when LanguageManager loads custom/modules/Calls/Ext/Language/en_us.lang.ext.php which includes the original field label
