fix: static page generation issues with language

LIIKUNTA-372.

Currently, the Sports app did not fail, but the Hobbies and the Events did.
This was because there was a different kind of locale handling:
The locale which was destructed from the context was set to null.
Now there is a fallback language set when the context locale is null.

The issue was easier to find and understand,
when I understood where the error was printed.
The error was our own message from the Apollo-Client's ErrorLink.
If the operation-variable from the onError-handler was printed in the console,
the actual error place was shown!
