fix: unattended component reload due to session changes (#407)

* fix: unattended component reload due to session changes

When the session is updated, status goes back to loading then
authenticated or unauthenticated. session.accessTokenExpires may also be
updated.

This triggered various component refresh at unattented times, and brake
the user experience.

By splitting to only what's needed with memoization, it will prevent
unattented refresh.

* review: change syntax
