Remove hacky replaceL behavior

[mattcoley]

This behavior has been here since initial commit but is pretty strange. Basically if we detect the format is a Java format rather than strftime format, we return the Java format back but replace all LLLL instances with MMMM. This means we can't manually specify LLLL when that is the appropriate format we want.

Probably had something do with python compatibility? Worth checking for differences in any case.

[mattcoley]

That's my plan. I am not sure how this would affect python compatibility since python would be using the stftime format with %, not the Java datetime format that we convert the strftime into.

I ran the diff report 5 times. The only diffs were expected. Languages that have genitive months are now properly using the genitive format.
