Repoquery the test repo in prepare phase

We check it before running tests
https://github.com/fedora-ci/mini-tps/blob/main/mtps-run-tests#L174
but better fail sooner.

There's not much we can do when this problem happens.
We would need to disable the correct module but
that might (e.g. in python27 module case) break
other packages dependencies.
So just warn the user.
