More details about the fix to the testDuration failure (regression):

```

The test fails because if either nextTrack.session or thisTrack.session are None the if is false and the instructions inside it aren't executed. The check for None is needed because Python 3 doesn't allow NoneType comparisons (in Python 2 that was possible).
IIRC correctly in that test nextTrack.session has value 2 while thisTrack.session is None. That means the Python 2 version evaluates the if condition to true, while the Python 3 version in the first commit does not.
With this change both of the values of nextTrack.session and thisTrack.session are compared as int (if None, the value 1 is used for the comparison - as in disc session 1).

Regression introduced in 64dd9d843a.
