Dialog runs forever (EXPOSUREAPP-5493)

[mtwalli]

From the logs I see the callback when TEK is received is called ,but despite that the dialog was not hidden.
My best guess here it is a race condition where routeToScreen.postValue is navigating to the next screen and
showKeysRetrievalProgress.postValue never got the chance to have an effect.

Fix: showKeysRetrievalProgress.postValue is called before routeToScreen.postValue to guarantee it is called.

code lgtm.
We should keep an eye on it checking whether the implementation is sufficent for the issue
