Check methods for RedmineTicket

[mjagelka]

I created my own developer admin instance on http://m.redmine.org/hostings/new for Redmine testing purposes and I discovered, that some RedmineTicket methods are not working properly:

• change_status() does not work, the status is not changed despite successful status code 200 being returned
• both add_watcher() and remove_watcher() fail, because inaccessible authentication is required. This is strange as I used my admin auth. Authentication is required even when accessing http://domain.m.redmine.org/users.json directly via browser, pop up authentication window shows up not accepting my login.

These problems might be unique for this particular instance, but it would be good to inspect the user experience in this matter. Methods create(), edit(), add_comment() and add_attachment() seem to work as expected.

Thanks for opening this issue, @mjagelka. When I worked on RedmineTicket, I mostly used my own instance of Redmine in a Docker container: https://hub.docker.com/_/redmine/. All these methods were functionally tested and worked in that instance, so it's strange that they're not working in other instances. We'll keep this issue open to look into this at some point.
