[PATCH v2] test: test-lib.el: replace sleep-for with sit-for in notmuch-test-wait

When running emacs tests using emacs 23.1.1 the tests block (until timeout)
when emacs function (notmuch-test-wait) is called.

There is an emacs bug #2930 titled:
23.0.92; `accept-process-output' and `sleep-for' do not run sentinels

It seems this is still active in emacs 23.1; replacing sleep-for with
sit-for makes the tests work as expected.

The other function in loop executed in notmuch-test-wait: get-buffer-process
just loops through process list, returning matching process object (or nil
if no such process found) without doing any further processing.

By comparing Emacs 23.1 and 23.2 function wait_reading_process_output ()
(changes in do_display variable usage) it seems that this bug has been
fixed in 23.2.
