Do not delete POFiles when cleaning cache

- The problem was when cleaning and refreshing the component cache.
Due the fact that it deletes all the POFiles from the database
and creates them again, Tx was losing 'locks' and possibly 'watches'
of users, because of the db cascade mechanism.
- This patch allows TX to continue cleaning/refresh the component cache,
however without deleting the POFiles. It sets them as enabled=False
and hide them from the UI.
- Deleting a project or a component thought, still deletes the POFiles
that belong to it, as expected.
