Adapt worspaces service functional tests to the new testing base class
There is a functional test class for workspace service. We need to adapt it to use the new functional test base class and enable tests so they will be run in Travis
[TASK] Fix functional tests in WorkspaceServiceTest
Refactor WorkspaceServiceTest to reflect recent changes
