[4.0] Load default language overrides

[bembelimen]

Summary of Changes

On multilingual sites the translations of language strings falls back to the default language (when not in debug mode). But if you have created some language overrides this behaviour does not apply.

Testing Instructions

• Create a multlingual page
• Install and activate at least one additional language to en-GB
• Create a language override for a not existing constant like: TEST_CONSTANT="Test" for the english frontend language
• open the index.php of your frontend template and put: echo Text::_('TEST_CONSTANT');
• Switch to the 2nd language

Actual result BEFORE applying this Pull Request

TEST_CONSTANT is outputted.

Expected result AFTER applying this Pull Request

Test is outputted.

Just for my own clarity - we call loadLanguage instead of parse directly so it can go into $this->strings?

[bembelimen]

Yes, parse only returns the strings loadLanguage parses internally and put it in $this->strings. Important is, that we don't do it in $this->override otherwise we would override again and again but we just handle it like a normal ini language file.
