Fix for bug #29444: crash with partition refering to table in create-select

Browse Source 
Problem: creating a partitioned table during name resolution for the 
partition function we search for column names in all parts of the
CREATE TABLE query. It is superfluous (and wrong) sometimes.

Fix: launch name resolution for the partition function against
the table we're creating.
