In some case, a user can be authenticated on the identity provider
but do not have account on Messages. In this precise case, we know
display a toast to explicit what's wrong.
When a user tries to access to a message route when it is not
authenticated, it is redirect on the homepage and have to authenticate.
Now in this case, we redirect on homepage and persist the previous route
within a next query param, in this way, we are able to automatically
redirect the user on the right view once it is authenticated.
Notably, we try to reduce disk usage by standardizind on common
base Docker images. We also improve node_modules by reducing
duplicate dependencies and install speed.
