Title: Adding multi-value presence validation

Given that we are allowing multi-value for a given attribute, we
need to better handle the presence of that attribute.

Consider:

class MyModel
validate :contributor, presence: true
end

object.contributor = ['']
object.valid? == true

When in fact we likely mean for it not to be true.
