David Mudrak 9e3d352dee Improved handling of occupied target issue
If the target area already contains a form, we can't pick anything to
use there. If the user works in two windows or there are several
teachers modifying the same course, it can happen that the form suddenly
appears in the target area while we have the form picker still open. In
such case, we simply redirects the user to the target area instead of
displaying the pooky exception.
