reenable tests make them pass

[JJ-Author]

I disabled tests/test_databusclient.py because they fail and need fixing e.g. test_databusclient.py#L50
potentially also the tested routines need fixing

hi @JJ-Author I would like to work on this! can you provide bit of information regarding the tests.

[JJ-Author]

see this commit, I fixed the download test code a little such that the download tests actually work
d3ca19c

but also skipped 2 tests using the following annotation
@pytest.mark.skip

since they fail.

task is to fix the test code and if needed the client code as well such that the tests are meaningful and pass.
not sure if this is a beginner friendly task since it requires deep knowledge about the databus its datamodel (that changed) and the Databus API.

@JJ-Author Alright thanks for the context! May I know is there any docs available related to Databus API?
