PIM Alert checks fail if there are no active alerts

[biggles007]

If there are no active PIM alerts available then the MT.1029, MT.1030, MT.1031 and MT.1032 checks can't complete. You get the following error.

RuntimeException: You cannot call a method on a null-valued expression.

The test is assuming there will be an alert with an active status, which isn't always the case. The test is filtering for active alerts of the require ID which returns a null object which the test then tries to process, hence the error above.
