Fix failing tests

That's just a dependency problem. We need a more recent version of token. And for some weird reason that I don't understand, testbot checks out tagged releases, not dev snapshots.

See #2621644: Always use latest dev of dependencies. Will try to bump that again.

Releasing a new token alpha will help I hope but sometimes testbot is also slow in picking up new tagged versions. I was hoping to have the token tree/render cache stuff there done so we don't have further changes in that area but it's not quite there yet. But we should do that asap anyway.

So, that finally works. There's one strange test fail due to the sub-folder but it seems that should work, might be a core bug. This fixes it.

Committed. I'll disable sqlite and postgresql patch testing for now until we've figured out what's causing those test fails. Doesn't seem like a release blocking thing.
