create unit tests for rm (running, paused, restarting) errormessages
These integration tests were basically testing if a
decent error message was printed when attempting
to remove a running, paused, or restarting container.

Moving these tests to a unit-test to make the tests
not flaky (especially on the "restarting" container
test).
