License compliance detects licenses for the source branch only in MRs

Summary

License compliance reports "License Compliance detected [x] licenses for the source branch only" in pipeline's license tab, even when there is an associated Merge Requests which target branch has the same licences.

The pipeline view doesn't have the same context as the MR view, so there is no possible comparison between the source and the target branch. Therefore, the wording should not suggest it and rather state what's the result of license scanning for that coresponding pipeline only.

Steps to reproduce

  1. Create a new project
  2. Add files from https://github.com/CycloneDX/cyclonedx-php-composer/tree/master/demo/laravel-7.12.0/project
  3. Create a .gitlab-ci.yml file with:
include:
  - template: Jobs/Dependency-Scanning.gitlab-ci.yml
  1. Check the Dependency List for stored dependencies with their licences in the DB.
  2. Create a new merge request with any change other than the dependency files from 2.
  3. Check the pipeline view -> Licences
