The request seems to cause problems so blockingSubscribe doesn't seem to be a good choice here. This commit will replace blockingSubscribe by subscribe and modify the related code in order to be executed when the request succeeds.

however i was not able to see onDestroy being executed.

anyway, disposables won't be necessary when coroutine is used.

also: remove a useless outdated log line
