[Bug 1007973] [NEW] apt-add-repository --remove acts if it adds a repository even though it doesn't

[Seshiro]

Public bug reported:

When I run "apt-add-repository --remove" it prompts, that it's adding
given repository - which is obviously not the expected behaviour - after
the process has ended, the repository is gone - as expected.
