[pgpool-committers: 9795] pgpool: Allow reset queries to run even if extended queries do not end.

[Tatsuo Ishii]

Allow reset queries to run even if extended queries do not end.

Commit 240c668d "Guard against inappropriate protocol data." caused
reset queries fail if extended query messages do not end. This commit
fix that by checking whether we are running reset queries in
SimpleQuery(). Also add the test case for this.
