Buggy server selection logic

[ddurdle]

Seems there is some server selection buggy logic.

Out of 3 tested plex accounts, only works with 1. On another, it seems to get hung up parsing the server list with this error: 2019-03-04 13:51:27 - INFO :: MainThread : Tautulli WebStart :: Starting Tautulli web server on http://0.0.0.0:8181/

Then on the third, it gets past this but it is using the wrong API token against the wrong server so it is not able to retrieve the user list. The code is thinking it is talking to server 3 but it is talking to server 2 and vice-versa.

The official documentation from Tautulli indicates that error will occur if the identify number is wrong. I checked in the Settings and the numbers line up, so it must be using the wrong numbers for the API calls.

What are your (relevant) settings?

[ddurdle]

Found the issue. Apparently on some accounts, certain variables are not defined ('') and by casting to an int in the parameter fetching, this causes an issue and prevents the server list from populating properly.

I have made these return an appropriate value if not defined so that the server list will correctly populate.

See #5

Thanks a bunch for catching and correcting this.
