In the HA router's keepalived state change monitor tests, it was
expected that enqueue_state_change method will be called 3 or 4 times.
But after some changes in the keepalived_state_change monitor which were
done some time ago, it may be now that it will be called just 2 or 3
times:
- 2 when initial status will be "primary" and it will be just
transition to "backup",
- 3 when initial status will be "backup", then it will transition to
"primary" and finally to "backup" again.
To reflect those 2 possibilities, test was changed that it will expect
2 or 3 calls and will check only that last 2 will be always transition
to "primary" and then to "backup".
Additionally this patch adds some extra logging in that test so it will
be easier to check what was going on in that test.
