[ Merge of http://go/wvgerrit/154593 ] This CL updates the initial time used for reboot tests to be within the valid range used by OPK. Also, the fake clock is now synced with every use of the TestHost's clock function. Also, the OPK's system clock is no longer initialized to 0 because this caused some tests to set initial playback time to 0. That broke code that assumed a time of 0 mean "never". I also removed some log spam in the WTPI code. Bug: 222353528 Bug: 236317198 Change-Id: Ibdbdb2440454b9cf561cd9ec65ca3e40cf5a8d93
