If a site contains teams, they become inconsistent after export/import roles with "Delete data before importing" selected.

Steps to reproduce the issue:

1. Create a site
2. Create a team in this site
3. Export roles to a lar
4. Import roles from the lar previously created selecting "Delete data before importing".

Current behaviour:

Teams become corrupted (admins cannot execute any actions on them any more, see attached image teams-error.png).

Expected behaviour:
Teams working properly and no error in logs.

NOTE: This causes other related issues like admin users are not allow to delete a site containing teams.
