collection.add() doesn't properly prepare models.

[mikefranklin]

This Collection initializes models with an attribute. Create() works as expected, including the attribute in the object. Add() uses only the passed-in data.

A non-Firebase-extended collection returns the expected content using add():

I imagine this is because Backfire create() uses

model = Backbone.Collection.prototype._prepareModel.apply(this, [model, options]);

while add() does not.

It's not clear if the difference is a feature, or an oversight.

Try to contact backbone and investigate SO questions; see if there is any definitive answer to the roles of add vs. create. Then specify our version of these behaviors in the README and make sure we are consistent (which will probably be done as part of #10)

#100 addressed this issue. Will be available in the 0.5 release.

This was fixed in the latest release #115.

Thank you so much for your details on this bug, @mikefranklin! It saved me a lot of time.
