This reverts commit 09f37064dee76349ec693a4867b46bd27564481d.

* Nothing was done in this commit besides commenting out pending()
  tags in failing specs.  This did not fix the problem for multiple
  reported users.  Please run "ADAPTER=sqlite3 rake spec" in the
  dm-aggregates folder to see the failing specs.
