Model validation does not match ActiveRecord's expectations

[inghamn]

InRoad's models were written with a validation function that returns an array of errors. However, Blossom's ActiveRecord class expects the validate function to throw exceptions.

The custom error handling was removed from inRoad's ActiveRecord library back in 2015, but the models were never updated to account for this.

The models need to match their validation to what Blossom's ActiveRecord class expects. This means it will, in fact, only show one form error at a time, since the first exception will halt everything.

We'll need to address this in a future rewrite.
