Fix SshKeysDispatcher test failing on Windows

The `SshKeysDispatcher` tests that use the keys list command are failing
on Windows because they assume a Unix line ending after each key. But
the command will use a system line ending. So this fix uses system line
endings in the reference string for the assert, too.

In addition, two `assertTrue(false)ยด are replaced with a proper `fail`.
