Subject: [PATCH] gstinfo: fix debug levels being applied in the wrong order

Remove unneeded reapplication of patterns. Besides being
superfluous (gst_debug_reset_threshold already applies
patterns) it was also wrong and didn't stop checking patterns
after the first match (broken in 67e9d139).

Also fix up unit test which checked for the wrong order.
