[libsoup] cache-test: fix race condition

[Dan Winship <danw src gnome org>]

commit 164e49a27eeeedca800f466b0b14a4e61a162007

    cache-test: fix race condition
    
    The refcounting test had a race condition. Fix it by just waiting for
    the stream to be destroyed, rather than asserting it already has been.
