Need to add src to all paths to import pubmetric

[almanilsson]

I can not directly import pubmetric. I need to add 'src' to the filepath for it to import correctly

sys.path.insert(0, os.path.abspath(os.path.join(os.getcwd(), 'src')))

My temporary fix is adding a config file to the test directory which adds this to all test files imports.

@vedran-kasalica - is this solved from the perspective of pubmetrics in Workflomics?
