rearrange tests

apparently on 2.8 subscribe/psubscribe message isn't sent just after
subscribe/psubscribe command, but with some delay. I've got the following
from cpantesters:

    #   Failed test 'got psubscribe message'
    #   at t/restore_subscriptions.t line 32.
    # +----+-----------+--------------+
    # | Elt|Got        |Expected      |
    # +----+-----------+--------------+
    # *   0|'message'  |'psubscribe'  *
    # *   1|'sub'      |'psub*'       *
    # *   2|'foo'      |2             *
    # +----+-----------+--------------+

    #   Failed test 'got message from sub'
    #   at t/restore_subscriptions.t line 34.
    # +----+--------------+-----------+
    # | Elt|Got           |Expected   |
    # +----+--------------+-----------+
    # *   0|'psubscribe'  |'message'  *
    # *   1|'psub*'       |'sub'      *
    # *   2|2             |'foo'      *
    # +----+--------------+-----------+
    # Looks like you failed 2 tests of 9.
    t/restore_subscriptions.t ..
    Dubious, test returned 2 (wstat 512, 0x200)
    Failed 2/9 subtests

Which shows that message arrived before psubscribe.
