Addition of isInstance test of BackendSerial

[talagayev]

Fixes #4657

Changes made in this Pull Request:

• Addition of test_instance_serial_backend to test_base.py to check that the function works and the instance is correct

Currently I just create a variable of BackendSerial for serial_backend , which I use in FrameAnalysis(u.trajectory).run to display that it runs with the backend=serial_backend and also then check the correct instance of serial_backend

I wasn't sure here if I should check the instance of backend of the run() in FrameAnalysis(u.trajectory).run(backend=serial_backend), since then I would need to modify the code to get the instance of backend from run()

I restarted the failing job. The timeout is a known issue unfortunately.
