APIv2 tests: fix race condition causing CI flake #6978

A newly-added test in #6835 was flaking in CI with:

not ok 143 [20-containers] DELETE libpod/containers/SHA
500 cannot remove container as it is running - running or paused containers cannot be removed without force: container state improper

Root cause: DELETE being run immediately after container start.
Although the container is short-lived, it does take time to
run and exit.

Solution: wait for container to exit (should be quick) before
deleting. This gives us a new test for the /wait endpoint.

Also: tweaked some comments for readability, removed unnecessary
container ps, added actual container status checks, and added
actual message checks to another test that was merely checking
exit status.
