Fix incorrect free for last_message

Browse Source 
In commit a7305eb539 the last_message
field of the connection object was changed to be always non-persistent.
But there is a place on change_user path that still treats it
depending on conn->persistent flag. This will cause PHP crash after
com_change_user success when there is last_message set
