Prevent (caught) panic on login (#11590)

Browse source 
Unfortunately when the virtual session is released it requires that the
real session does not exist. This worked fine when sessions were only
saved at the end of request/response cycle however, now sessions are
saved proactively this does not hold.

The result is a caught panic in the logs during every log-in.  This
panic has no significant side-effects but should not occur.

This PR marks the virtual session as released when released and updates
it if the same session is released again.
