With the goal of reducing log spam, print only a summary 'Found stale backup journal' messages instead of logging within the inner loop. Previously, over 12k messages could be printed at a time from this function. Before this CL: - a backup was scheduled for each packageName from each stale journal - one (or two, if MORE_DEBUG) message was logged for each packageName in each journal file. After this CL: - packageNames are de-duplicated before scheduling backups or logging (it's not clear to me whether duplicate packageNames previously occurred, in practice). - one message is logged for the number (if > 0) of stale journals. - one message is logged for the number (including their names, if MORE_DEBUG) of packages. Bug: 161940947 Test: fewer 'Found state backup journal' messages printed Change-Id: Ia1343e4cea31feb1eba9da561d20736eb5df0a14
