New errors in cases where:

v.pff_variable in self.profile_only_variables 
and geotype in self.aggregated_geography

For example, the following variables from db-community-profiles out_acs.py produces all NULLs except for foreign born in CD 105.

{'pff_variable': 'ea_bchdh',
  'geotype': 'cd',
  'column_mapping': {'z': 'moe_bach_deg', 'p': 'pct_bach_deg'}},
{'pff_variable': 'fb1',
  'geotype': 'cd',
  'column_mapping': {'z': 'moe_foreign_born', 'p': 'pct_foreign_born'}}
