[BUG] 2FA problem: Does not take authorization in the first go

Actual behaviour

-When you authorize using 2FA (here: via Free OTP) you have to perform the authentication procedure twice.

Expected behaviour

-The app should accept the authorization the first time it is presented

Steps to reproduce

1. Start OwnCloud app and connect to the cloud
2. You get redirected due to authorization expiration, so you enter your credentials in the Web browser that is opened for you, then you create the token for 2FA (here: via Free OTP) and enter it. In the browser the cloud opens up and also a popup comes that asks you "open in app?"
3. Agree to opening in the app, OwnCloud app comes up again, but: complains about expiration once more, so go back to step 2 and repeat everything. This time the autorization gets accepted.

Can this problem be reproduced with the official owncloud server?

Start by reproducing the flow in the OwnCloud Android app: expiration, browser credentials, Free OTP, and the "open in app?" handoff. Compare the first and second authorization attempts and inspect the app and browser authorization transition. Done means a valid 2FA authorization is accepted on the first attempt; add logs if reproduction requires more evidence.
