Fix log checking in PRH so that only entries generated during test execution are taken into account.

- fixing "Should not send PNF ready when DMaaP event is not JSON array" test that was passing due to checking log entry generated by a previous test
- improving logs generated by keyword waiting for log entry
- changing 'find log entry' to 'wait for log entry' with explicit timeout setting
- adjusting timeouts for waiting for log entries to appear (20s is enough when prh workflow execution is scheduled every 10s)
