pgAdmin III commit: Extensions have no owner

Extensions have no owner

Even if there is a pg_extension.extowner column, there is no way to change it
with ALTER EXTENSION, and to set it with CREATE EXTENSION. dlgExtension
doesn't even show it.

So, we get rid of the owner handling.

Per report from James B. Byrne.
