Description

During root tablet assignment, unflushed mutations are recovered from the WAL, and then compacted out. This records a new WAL entry for the root tablet, and recovery is immediately started. This interferes with writing out the minorCompaction started and minorCompactionComplete flags. We don't want to write out anything to the WALog until the tablet has been brought online.
