Fix TestSummaryProvider.

Browse Source 
assert.Contains() checks if its second argument (which is supposed to be
a single element) is contained in its first argument (which is supposed
to be a slice/map etc.) The third and following arguments are supposed
to be message and args for the output in case of failure.

Because of this bad form, a failure was hidden, the system container is
named "misc", not "system".
