Will override email, display name and avatar URL with the values
provided in 'context.user' structure of the JWT token.
Settings will no longer be used to retrieve local display name,
email and avatar URL. Now those values will be obtained from
the /features/base/participants Redux state.
fix(jwt/middleware): use const for default name
fix: wrong default display name on web
ref(base/participants): remove getDisplayName functions
ref(jwt): do not accept unknown user fields
