mandos-ctl: Fix bad test for command.Remove and related minor issues
The test for command.Remove removes all clients from the spy server,
and then loops over all clients, looking for the corresponding Remove
command as recorded by the spy server. But since since there aren't
any clients left after they were removed, no assertions are made, and
the test therefore does nothing. Fix this.
In tests for command.Approve and command.Deny, add checks that clients
were not somehow removed by the command (in which case, likewise, no
assertions are made).
Add related checks to TestPropertySetterCmd.runTest; i.e. test that a
sequence is not empty before looping over it and making assertions.
* mandos-ctl (TestBaseCommands.test_Remove): Save a copy of the
original "clients" dict, and loop over those instead. Add assertion
that all clients were indeed removed. Also fix the code which looks
for the Remove command, which now needs to actually work.
(TestBaseCommands.test_Approve, TestBaseCommands.test_Deny): Add
assertion that there are still clients before looping over them.
(TestPropertySetterCmd.runTest): Add assertion that the list of
values to get is not empty before looping over them. Also add check
that there are still clients before looping over clients.
