Autopilot tests modify databases during test setup

Some autopilot tests perform their set up editing the database of the apps.
We have found that it causes a lot of problems, because the database format can change. And anyway, that's not the kind of set up we should be doing for black box testing.

We should try to set up the tests by just placing files at folders where the user has permission, or by performing other actions that a real user would perform.
