Fail in last PR regarding the use of json module

[ValentinBuira]

There is a typo in my last PR regarding the use of json module

I used json.loads with a s instead of json.load that support de serializing python object and not string

Every use of workspace_service failed in the plugin because of that

Fix is ok. We need to update tests to catch these errors for workspace_service method

I preffer to cancel this PR and do just few things (or rerevert commits)

• remove just monhtly contributors test manually, do not revert changes (I see there some added print)
• there was also some minor improvements by me and @VitorVieiraZ
• add your testing function for workspace
