* remove incorrect check for cross-signing
SETUP_ENCRYPTION tries to set up everything (4S, cross-signing and key backup),
rather than just setting up encryption, as its name would imply.
crossSigningReady == false happens when the user's device isn't verified, so it
should trigger VERIFY_THIS_SESSION rather than SETUP_ENCRYPTION
* reorder conditions in allSystemsReady to match the order in the if statements
* explicitly handle secrets missing from 4S
rather than falling back to the SETUP_ENCRYPTION catch-all. Also, remove
SETUP_ENCRYPTION since it is no longer used.
* convert button handlers to switch statements for consistency
(almost) all the other functions that use make decisions based on Kind use
switch statements
* update i18n (remove obsolete string)
Any UTs for vector-web layer components or functionality should go here.
This used to contain the UTs for notifications before they got moved to react-sdk.
