[Translation][transChoice] issues with imploding and escaping plurals

Changes introduced here return "|" when the plurals from a *.po file are empty strings, this happen because the PoFileLoader.php is imploding the plurals with "|" and will generate something like "||" if the translation has empty plurals strings.
The commit mentioned above understand double pipe as a escape character and act wrongly returning "|".

Hey, thanks for your report!
There has not been a lot of activity here for a while. Is this bug still relevant? Have you managed to find a workaround?

I guess we can close here as the transChoice() method has been removed from the Translation component.
