Niels de Vos 701b5d7ecb e2e: Add early return in Context() for disabled tests
Some parts of the Context() seem to get executed, even when BeforeEach()
did a Skip() for the test. By adding a return inside the Context(), the
tests should not get executed at all.

This was noticed in a failed test, where upgrade was running, eventhough
the job was executed as a nornal non-upgrade one.
