build.opensuse.org shows the "project maintainer, not package maintainer" warning incorrectly

[MeggyCal]

Issue Description

OBS shows "You are a project maintainer but not a package maintainer. This package has 1 package maintainer assigned. Please keep in mind that also package maintainers would like to review this request." in my requests even in projects where I don't have any rights and the only thing I can do with the request is to revoke it.

Expected Result

The warning should not be displayed in cases where it does not make any sense.

How to Reproduce

1. On any OBS instance with web UI, create a SR to some package where you don't have maintainer rights.
2. Go to web UI and view the request.
3. At the bottom you will see the warning, but no "Accept request" button (only the "Revoke request" one).

I suspect the request must be from a project which you maintain (home branch or some different one) to an existing package which has at least one package maintainer assigned.

Hence I might guess that OBS sees that I am the maintainer of the source project and that the target package has some maintainers and mixes it up. If I am also a maintainer of the target project, this turns out to be correct behaviour, but if I am not, the banner is incorrectly displayed anyway.
