Some improvements to generator behavior

Some assorted generator improvements.

- Converting `belongsTo` and `hasMany` from more formats when generating models. (Previously it wouldn't add model to `needs` array of test unless already dasherized).
- Pluralizing attribute name when of type `hasMany`.
- Tests for the above and more.
- Adapter => Serializer in the Serializer test examples to match the other files.
- Go through a variable in the view test example like in all the others.
