Title: Fix loaders to check if resource exists.

This was mentioned in #5797.

The problem is that some translation loaders throw exception when translation resource is not found, some produce warnings and some ignore this and return empty catalog.

After this fix, all of them will throw exception in such case. But still, some of them will throw `RuntimeException` and some `InvalidArgumentException` which is not perfect, but still one step in good direction.
