[BUGFIX] Prevent broken page module state

In case content elements exist in the database,
having a CType for which no TCA exists, e.g.
because an extension providing this CType
has been deactivated, no more UndefinedSchemaException,
is thrown. This allows an editor to properly
handle the situation as before.

Note: Such elements are displayed with an
"INVALID VALUE ("INVALID_CTYPE")" badge.
