When closing a statement, we may send DSQL_close before DSQL_drop [JDBC639]

When closing a statement, when the result set wasn't completed yet, the current code will first close the result set, which can result in a DSQL_close being sent, followed by a DSQL_drop. Investigate if we can skip sending the DSQL_close in a clean way.

Restrict to only Jaybird 5; this isn't very important.
