When updating the categories, if by any chance there is a loop in the
category hierarchy, the current code was falling into an infinite loop.
With this commit, the graph loop is broken by clearing a parent_id, and
if the resulting module category path is wrong, a clean new one will be
recreated anyway.
This allows unblocking uncomfortable situations where people cannot
update the modules list any more. In 15.0, [a check][1] has been
introduced to prevent the existence of recursive categories, but as it
is a python check it doesn't prevent corrupted data to remain corrupted.
