CI: Do not rebuild Docker images for test builds for new branches

New branch considers all files changed. We don't want to rebuild all
docker images for new branches; that's just a waste of time and energy.

There is a better way for future -- a much better fine-grained control
may be obtained by running secondary pipelines.

fixes #212
