Nt/account switch fix

What does this PR?

After testing a number of scenarios and trying to recreate the environment being faced by users, added a bunch snippets to help avoid embarrassing situations

1 - purges malformed accounts 2 - logs out of app instead of logging into malformed account 3 - rearranged logout structure to avoid creating an undefined auth data state 4 - moved isLogingOut state to uiReducer so it gets reset on every app launch if routine is interupted for some reason

Screenshots/Video

Added account verification mechanism on startup, account switch and logout if malformed keys data is detected. instead of wiping account data without notice, app now asks to verification and assist with prefilled username
