A patch for Bug#11765297 (58251 - archive_plugin and blackhole_plugin

Browse Source 
fails when running with ps-protocol).

The problem was that when running in --ps-protocol mode mysqltest.cc
didn't close created prepared statements. So, the plugins could not be
unistalled because there was a prepared statement using them.

A fix is to add a dummy statement that forces mysqltest.cc to close
the last prepared statement (which uses a plugin-defined table).
