Fix OwnerName function to work with schemas 

We incorrectly try to use relation cache to find particular schema's owner and
when we cannot find the schema in the relation cache(i.e always), we automatically
used current user as the schema's owner. This means we always created schemas in
the data nodes with current user. With this patch we started to use namespace
cache to find schemas.
