test: Fix test.service cleanup in TestServices
test: Fix test.service cleanup in TestServices

If a test fails at the "wrong" time, it may happen that test.service is
still enabled. The previous cleanup only stopped it, but not disablled
it again, so that the next test retry would unexpectedly find
test.service already enabled.

Clean up more thoroughly.
