Check -files with specific revision checks all revisions

Please describe what you are doing to trigger the bug:
Scheduled a task to check the last revision of a backup with the -files option

Please describe what you expect to happen (but doesn’t):
Only the latest revision is checked

Please describe what actually happens (the wrong behaviour):
All revisions are checked

Here is the output:

Running check command from C:\Users\YYY/.duplicacy-web/repositories/localhost/all

I’m using the Windows Version 1.5.0

-tabular implies all revisions. This option is added automatically, but you can avoid it by specifying -id Allgmein -r 7.
