    tests: Await for graph switch before testing open fop count

    In performance/open-behind.t, a test for open fop reaching the brick is
done by
    switching off open-behind and performing a read operation. If the read
operation
    is performed before a graph switch, the read happens on the old graph and
hence
    open does not get accounted in the brick.

    To overcome this EXPECT_WITHIN 10 seconds has now been added to ensure that
a
    graph switch has happened. The read operation happens subsequently after
the
    graph switch.

    Cleaned up a "No volumes present" message from stderr while doing this.
