Make release jobs run also when merging to master

The root cause of the bug was that using ANDs if the job is not in the context of merge request (returning false) it'll never checked the second clause, whether the current branch is master.

We turn ANDs to Gitlab's if rules which makes these clause be evaluated independently thus, logically turning the ANDs into ORs.

As docs explain in https://docs.gitlab.com/ee/ci/merge_request_pipelines/index.html#enable-pipelines-for-merge-requests-for-specific-jobs, this reads like list of situations where a specific job will be executed.

This left version 0.0.2 unpublished, so what I'll try next is merge this MR and then, push a new tag called fix-0.0.2. This should trigger all the jobs in the pipeline but read the VERSION of the package from setup.py so publishing 0.0.2 in PyPi instead of fix-0.0.2.
