fix(router): do not create sessions for /_health

When the /_health endpoint for the docker container
healthcheck was introduced, it seems that it was
forgotten to exclude that route from the session
creation. As the healthcheck runs quite periodically,
this created a huge amount of session entries in the
database. This commit excludes the route from
session creation.
