[BUGFIX] Consider translated pages in workspaces

This issue was raised that translated pages do not
show up in the list of records to be published/staged,
as translated pages are in the same table.

So, page handling needs to consider l10n_parent fields,
and check for the UID/l10n_parent, whereas other records
(like pages_language_overlay before) only are checked for
the "pid".
