Log:
[Master] Fix TestRegionChecker

Author: liyintang

Summary: There was a bug in the TestRegionChecker. In the unit tests, the test 
function tries to verify whether avDetDayAfter contains all the re-assigned 
regions. However, the ROOT region will not be included in such collection based 
on the design of the HRegionChecker. Therefore, the fix is to exclude the ROOT 
region from the checking.

Test Plan: will run this unit tests multiple times to verify
