Fixes bug #14569. When no db is selected as current and we do create procedure db.sp()...

Browse Source 
we changing current db temporarily and restore it when sp is created. however thd->db
in this case becomes empty string rather than NULL and so all checks of thd->db == NULL 
will be false. So if after this we'll issue create procedure sp2()... without specifying
db it will succeed and create sp with db=NULL, which causes mysqldto crash on 
show procedure status statement.

This patch fixes the problem.
