[snmp|agent|test] Test case info and cleanup
1) A test case failed due to the times retreived by get(snmpEngineTime) reported to large time diffs (this is basically a sanity check). Added some more info about time(s) to see if there are some "gaps" somewhere. The problem occurred on a slow Virtial Machine. 2) A previous (failing) test case failed to cleanup after itself (see above), which caused later test cases to fail. Specifically, the app top supervisor was not terminated, which caused the start agent function to fail (basically already_started).
