Skip tests for ldapsource with python >= 3.7 Until someone works on fixing these, this should make our CI green again. I tried to use setupModule() to check for python version, but pre_setup_database() is apparently called even when a SkipTest exception is raised there. So handle this in that method.

if not rql('CWConstraintType X WHERE X name "RQLUniqueConstraint"',
           ask_confirm=False):
    rql('INSERT CWConstraintType X: X name "RQLUniqueConstraint"',
        ask_confirm=False)
