Fixed bug #56778: languageExceptionUids not working with RealURL 1.12.8
[BUGFIX] Expire path cache when adding new page translation

Previously, adding a new page translation did not clear the path
cache. If a path cache entry already existed for that language
the url was not updated to reflect the new translation. This
change ensures that the path cache is also expired when adding
a new translation.

[BUGFIX] Deleting of single entries of decode/encode cache

Deleting of single entries of decode/encode cache fails sometimes since
the items are identified by hash and not by id. Since there is an intval
for the hash, the int and the hash don't fit together which results in
strange behavior.
