Nothing about `fetch` in model docs

[milesmatthias]

I'd frequently do something like:

model.create(); model.save(); allRecords = model.all();

and allRecords.length would be 0. This was really confusing until I looked at the source and saw I needed to fetch all of the records first.

I'll try to make this more clear soon. Thanks for the input.

added a bit. nothing extensive, but should give people enough of a hint
