Catch EGS authentication errors

[alkazar]

When EGS token expires, the following error occurs:

Server error:

Error when running the same command from the cli:

[gamer@chimeraos ~]$ legendary list-games --csv
[cli] INFO: Logging in...
Traceback (most recent call last):
  File "/usr/bin/legendary", line 33, in <module>

    if not self.core.login():
  File "/usr/lib/python3.10/site-packages/legendary/core.py", line 187, in login
    raise ValueError('No saved credentials')
ValueError: No saved credentials

We should catch the error and handle it better than just showing a 500 internal server error.

I may have hit this today and posted in the discord help section. I'll check the CLI later. Indeed it's very frustrating when you don't know why it's not working.

This should be fixed in the latest release.
