Relationships not evaluated

[tschmidtb51]

The current version (might be v3.0.0-beta-39-g0905824) does not evaluate purls given in a relationship item.

@tschmidtb51 Can you describe briefly what the expected behavior should be?

[tschmidtb51]

All purls in the following example should be found:

    ]
  }
}

Currently, pkg:no-valid-type/any-other is missing.

@s-l-teichmann Thanks for looking into that - I didn't realized this since I looked at the code when finding the issue (and didn't check the example against the running program).
