Use a fresh copy of query_list when making a second plan in GetCachedPlan.

The code path that tried a generic plan, didn't like it, and then made a
custom plan was mistakenly passing the same copy of the query_list to the
planner both times.  This doesn't work too well for nontrivial queries,
since the planner tends to scribble on its input.  Diagnosis and fix by
Yamamoto Takashi.
