message:
Bug#36004 mysql_stmt_prepare resets the list of warnings

Although the manual says that "the list of messages is reset
for each new statement that uses a table", the list of messages
is being unconditionally reset for prepare commands.

The solution is to enforce that the prepare command will only
reset the message list if the statement being prepared uses
a table or a warning is pushed.
