MailMetadataIT.metadataOnNewChange failed when it was executed against
NoteDb, because of a timestamp mismatch. The NoteDb timestamps provide
precision only on second level, while the timestamp in the mail header
includes milli seconds. Fix comparing those timestamps by setting a 1s
clock step for the test.
