Application crashes after encountering streamer that doesn't exist #706
Description
Describe the bug
On startup, application will load all the streamers, if one of the nicknames isn't recognised a message something like 'Streamer with this "nickname" doesn't exist' would be displayed in the terminal and that is a very nice feature. However, now on startup, the application encountering a user that doesn't exist just crashes instantly and terminal closes.
Steps to reproduce
Open config file (example.py), add a streamer nickname that doesn't exist and start the application.
Expected behavior
It used to display message that user doesn't exist, now it crashes.
