Scripts fail if user has access to same project in different groups

Test Case

1. Create or import a project into a group you have access to.
2. Fork that project so that's in your personal space too.
3. Trying to run a script will give an error like:

./irker.sh gnome-tweak-tool \#test Setting up irker integration for gnome-tweak-tool (4595 1547) gnome-tweak-tool not found using https://salsa.debian.org/api/v4 service

The problem is only a simple "search" is used and the scripts doesn't allow specifying what group to search in.

(Perhaps a project decides it wants merge proposals for everything. In that case, it definitely makes sense to allow same-named projects. Or maybe someone wants to work on something but not push it to a "wip" branch at the main repo yet.)
