[#53334885] Updates backbone to 1.0.0

 - Notable changes from 1.0.0:
  - The default action after fetching a collection was changed from #reset to #set (#set is renamed #update).
    We pass option.reset = true unless otherwise specified to maintain the 0.9.10 behavor. See #fetch, #fetchAll
  - Collection#reset no longer has a guard against undefined `models`. We now pass models || [] when calling super
    from chorus.collections.Base
  - sync success/error callbacks are already wrapped into the 3 parmeter form, so we no longer need the wrappers
    in our custom sync
