Deleting a theme brakes profile page theme for new users

[Cecilia Vela Gurovic]

When deleting old theme and there is still one institution with that theme set:

if a new user is created before the institution theme is updated to new one, the profile page for new user will be created with the old theme. As the old theme is not available any more, the profile page will be displayed with default theme and will only be possible to change through the DB.

Actually the user can change their profile page theme by editing their profile page - if it is an obsolete theme they will be prompted to choose a new one
