Py (addons) i18n: fix memleak, enhance msgid lookup.

Probably did not happen yet (since nobody uses addons translations...), but there was an
nice memleak during creation of translation ghash in case a same msgid/msgctx would be
added more than once.

Also, no need to allocate (and free) a temp key each time we lookup a msgid, we can use
given const strings directly here!
