This patch includes a unit test which checks the memory address
of the $env hashref in middlewares before and after
Koha::Middleware::Env is applied.
It succeeds when the same $env is maintained before and after
this middleware. It fails if the $env has been overwritten with
a new hashref (as evidenced by the new memory address for the
hash).
