[pgpool-committers: 209] pgpool: Fix following cases that do not uses query cache:

[Tatsuo Ishii]

Fix following cases that do not uses query cache:
1) A write command is executed.
2) In an explicit transaction, a write command has been executed and
   the transaction closed.
In those cases, if no explicit transaction starts, query cache never
used.
