Fix crash when changing seasons & improve error page (#94)

Related to #64 

If an error occurred while querying for a season's episodes, the app
would crash instead of display the error message.

This PR fixes the app crash, but not the underlying query issue. It also
changes the error page to show a button for sending logs to the server
immediately.
