Adjust timeout value in test_client_timeout

Per information filed in bug (and related bugs referenced in the
report) it appears that in TestObjectController.test_client_timeout
having a matching timeout value for both self.app.client_timeout
and SlowBody() appears to work however, as expected, a smaller
value in self.app.client_timeout also works where a larger
value fails.  With that short test combined with speculation and
related fixes, seems reasonable to merge what is suggested in
the bug report, drop the self.app.client_timeout to 0.05

Fixes Bug #1316716
