This is a prevention fix for #2438 because we still couldn't reproduce. But users are facing race condition where checkin plist file is deleted after a new checkin is written to the file. So we move the plist deletion call to the first step of resetting checkin during app start. Because FIRInstanceID init call should be always before first checkin call got issued.
Also add two more logs which helps provide the timeline when checkin plist file is written or read.
