Fix unstable proced test

Fix unstable proced test by omitting the revert parameter in
'proced-update'.  This was caused by the process being refined on
exiting between the initial 'proced' call and the successive
'proced-update' call.  This resulted in proced skipping the refinement
in 'proced-update', causing all processes to be shown again and the
test to fail.

* test/lisp/proced-tests.el (proced-refine-with-update-test): Do not
use revert parameter when calling 'proced-update'.
