Remove tests for installing packages via multiple paths

When multiple paths to the same rpm is given, I believe there are two
valid approaches:
    1. Fail because of conflicting requests
    2. Install one of the packages (if they have the same checksum)

Currently dnf fails because of conflicting requests, but I don't think
there needs to be a test for that, since the other approach is not
strictly bad.
