Cannot post UTF-8 chars in comments to notes and changesets

[Zverik]

See https://github.com/openstreetmap/operations/issues/524

For example, If I go to https://www.openstreetmap.org/note/2639402 and try to comment with "test with ccaron č letter" I get 401 Unauthorized. Same if it contains other national letters like "ČĆŠĐŽ". If I use just plain US-ASCII, it works fine.

Probably related to ad6c0d3 as @mmd-osm found.

Issue is triggered as a side effect of ad6c0d3 - reverting this commit fixes the issue in a local test.

Affected: Some endpoints which are being handled by the Rails port, when using OAuth1.0a authentication.

It also causes notes to be created as anonymous user despite being logged in: https://www.openstreetmap.org/note/2639681 vs https://www.openstreetmap.org/note/2639682

Yes but the other one was raised earlier, just in the wrong place and I didn't realise until I wondered why a new ticket had been entered s I moved it over here which gave it a new higher number.
