[Project Oriented] Impossible to delete "broken projects"

When you import a project with old (unsupported) structure you'll get useless javascript error (screenshot). The problem in this case is that it's impossible to delete the project from the UI (because to delete the project you have to OPEN it first,which is impossible in this case).

This is not an edge case - we can expect people will be trying to import all kinds of "OLD" (pre 7.0) projects they have. When such a project is imported, it's impossible to delete it.

It is possible to delete it manually from command line (see workaround), but the steps are relatively complex.

We've got a failing community selenium test which is failing because of this error . I marked it using @Ignore annotation. Please remove the Ignore when fixing this (and possibly update the test or contact me (jhrcek) for assistance).
