Title: QueryID not cleared when calling close()

The following procedure causes an issue:
1) Create a new DB_MYSQL instance
2) Make a call to query()
3) Make a call to close()
4) Make another call to query()

Line 219 still sees a QueryID as existing so when it calls warnings(), Line 401 causes an error because LinkID is false and mysqli_warning_count is not expecting a boolean parameter.
