[PBCKP-259] fix for 'ERROR: Cannot create directory for older backup'… (#526) 
* [PBCKP-259] fix for 'ERROR: Cannot create directory for older backup', rewrite --start_time implementation
* rewritten 5f2283c8de
* fixes for several tests
* disabled tests.merge.MergeTest.test_merge_backup_from_future and tests.restore.RestoreTest.test_restore_backup_from_future as incorrect for now
