fix(forgejo): Revert "Improved auto-detection"

This reverts commit 41c5ec9, because
the auto-detection done in it turned out to be unreliable. The old
method might be a tiny bit more expensive, not as nice, but it is
reliable, because it does not depend on the Forgejo instance
configuration.

Also re-enable the tests that were failing due to the naive
auto-detection breaking because the cookie name was changed server-side.

Fixes #91.
