add test for 315.1.9

hrpsys 315.1.9[1] solves significant improvement on failure if the test code

- update  findComps() wait for at least ten times ( 10 sec ) before finding RTC
- if findComps() could not find RTC successor findComp() did not wait for 10 sec
- test code[2] calls findComps() before calling other RTC methods
