`cargo test` output contains confusing errors

[rvolosatovs]

Ever since #312 was merged (determined by bisecting) cargo test prints confusing errors to the log:

The only reasonable solution seems to be disabling server-side logging, which in turn will complicate debugging.
If the test case was isolated, we could disable logging only for that specific test case.

I'd propose splitting the invalid token tests into a separate auth unit test and disable server-side logging for that specific test case as part of the effort.

Blocking #322

[puiterwijk]

As far as I can see, all the tests are passing?
It says test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 5.88s, and exits with code 0?

nvm, output is just confusing , will fix in #324
