This field will be used as a deterministic id of multiaccount on
status-react side instead of master key address. The reason why
it is calculated as sha256 of public key is that this way is
already used on keycard side and it will simplify integration.
Rename keycardKeyUid to keyUid
As long as this field will be present in all multiaccounts from now on it
shouldn't be named as keycard specific.
