GUI build: ensure all tests are being run

As a developer I would like the GUI build to run all of the unit tests.

Currently at least the following tests are not being run:

• model.tests
• logger.tests

We should have a check that projects ending in .tests appear in the client.tycho.parent file, and fail the build if this is not true.

Found when creating script generator build.

Acceptance criteria

• GUI build fails if any test module is not listed in client.tycho.parent/pom.xml
• GUI build is running all tests & therefore passes
