Check that version increases when adding packages to testing
When we try to compute_groups for a group which has a source or a binary with a lower version than testing, throw an exception. In the cases where this can happen, the exception is caught. In other cases, it is not and it serves as an assert. This can only happen when there are multiple candidates (from multiple suites) changing the same source or binary. This should fix the ordering issues tested in these tests: - tpu-unstable-binnmu - binnmu-tpu - tpu-with-unstable-binnmu With this change, it should be possible to accept binNMUs from *pu again.
