Title: Close #242

See https://github.com/mbleigh/acts-as-taggable-on/issues/242

Rails blows up if anything other than column name is given explicitly in the group option. I've changed this to use the `having` method. This is the correct use of the AR query API.

I've also added a failing test in my own rails fork that demonstrates the issue:
