Summary of changes

• Fixed the tests to match some new workspace changes, like the removal of phovea_[core|clue|...] repos a long time ago, or the existance of the /dist/tsBuildInfoFile.
• Added the build-only job to run in all branches, that's how this was missed in the first place. @anita-steiner was it intended to not be run in any branches? If yes I can remove it, but I think we should keep it right?
  • I couldn't solve the issue with the tests not being able to be run as the phovea:... generators are not found during the tests? Therefore, most tests are failing due to You don't seem to have a generator with the name “phovea:_check-own-version” installed.. I can't really put my finger on the reason, but it might be due to the way tests are run/the testrunner resolves stuff. For example, ssh into the container and yo phovea:_check-own-version works as expected.
