Incorrect or correct security phrase for setting up recovery silently fails

[tuxayo]

Steps to reproduce

1. A prompt suggests me to "set up recovery". When I put my security Phrase and hit "continue" it just closes with the message suggesting "set up recovery" still there.
2. If I use my security key, the UI tells me it's correct but when I hit "continue", the same happens as above.
3. In the JS console I see among other things:
   Olm device has private keys and they are saved in secret storage; doing nothing
   Not saving backup key to secret storage: no backup key
4. When I put a wrong security phrase, I get in the console "accessSecretStorage: error during operation Error: Error decrypting secret m.cross_signing.master: bad MAC"
5. With the UI just closing the modal and the prompt "Set up recovery" still there.

That's when I found #13180

Outcome

What did you expect?

Happy path working.
Unhappy path not having a JS error and instead having appropriate feedback in the UI.
