transaction: handle missing file in backupentries (instead of using entries)
The case where a backup of a missing file was requested was previously
handled by the 'entries' list. As the 'backupentries' is about to gain
ability to backup files outside of '.hg/store', we want it to be able
to handle the missing file too.
Reminder: using 'addbackup' on a missing file means that such file needs to be
deleted if we rollback the transaction.
