  Log Message:
  -----------
  Allow key-less polystring translation

If PolyStringTranslationType.key is missing, we now apply standard
fallback mechanisms (fallbackTranslation / fallback). Also, if key
cannot be resolved, we look not only at fallback property, but at
fallbackTranslation as well.

Revived inactive LocalizationTest.

Resolves MID-6881.
