>    Affects Versions: 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.5.0

> 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.
