Some project issues records have become separated from their project

Some project issues records have become separated from their project.

Probably an error during and update though there were no error reports.

The pid (project id) fields had nonsense values in them, i.e. values not in the projects_projects table. All should have been in the simulisticscomcore project (only two other issues anyway).

Used myphpadmin to edit the tables by hand.
