Attempt to fix a rare random test error in main.information_schema.

Browse Source 
Add missing REAP to the test.

A later test failed with strange incorrect values for COM_SELECT
in information_schema.global_status. Since global_status is updated
at the end of session activity, it seems appropriate to ensure that
all background connections have completed before accessing it.

(I checked that the original bug still triggers the test case after
the modification with REAP).
