Fix type.match crasher

[patocallaghan]

Ember Data allows you to do: name: DS.attr() without specifying a type for the attribute.

In some circumstances having no type set would cause your tests to crash on the following line: https://github.com/danielspaniel/ember-data-factory-guy/blob/master/addon/converter/fixture-converter.js#L32 because this.transformKeys was true but type was undefined.

if (!this.transformKeys || type.match('-mf')) {
  return this.noTransformFn;
}

Adding position: attr() caused the employee acceptance test to break. This fix makes it pass.
