tests/frontend/workspace.py: Test that all elements build with workspace in playtristan/fix-workspace-build-all

Tests that the target is still built even when a workspace is open
on a runtime dependency of a build-only dependency.

This adds the regression test provided by Matthew Yates for issue #919
