🐛✨ Ensure adding/deleting node is thread safe

[sanderegg]

What do these changes do?

• some findings from ✨ Allow selective start/stop of dynamic services (⚠️ devops) #3449 were splited in here:
  • adding nodes concurrently would fail to be correctly saved into the databsae, leading to inconsistencies (e.g. creating hundreds of new nodes in a project would only save some tens of them) --> this is fixed by patching the workbench instead of replacing the whole project with an outdated project (the process of patching is locking the project in the database while being updated, preventing any other reads.
  • deleting node was not updating the database, which was relying on the frontend to save the project. This is now done 100% in the backend and also by patching the workbench

This goes along the lines needed for ITISFoundation/osparc-issues#756

Next steps will be to:

• change links
• change node names
  through the backend as well.

Bonus:

• added carryforward flag to codecov, in an attempt to not have reduced tests now that unit tests are skipped some times

Fantastic
Please check some minor below

THOUGHT: I find shame that we go back and forth from UUID to string and then back to uuid ...

When converted to the str we lose the guarantee of a valid UUID downstream ...

[sanderegg]

yes, did you see I changed the syntax of delete_node?
