Title:
  Error when renaming a network

Status in OpenStack Dashboard (Horizon):
  New

Bug description:
  The error is on stable/newton.

  On stable/newton on the /project/networks/ page, when trying to rename
  a network we get both a success message (in green) and an error
  message (in red) saying "Danger: There was an error submitting the
  form. Please try again.".

  The logs show:

  Internal Server Error: /project/networks/e529df34-bf03-4775-be70-5f377c856334/update
  Traceback (most recent call last):

      d['subnets'] = [s.to_dict() for s in d['subnets']]
  AttributeError: 'unicode' object has no attribute 'to_dict'

  And we do not see the name change.
  When we simply refresh the /project/networks/ we see the name was changed with success.

  When debugging with ipdb, /api/neutron.py", line 101, in
  Network.to_dict we can see that after `d =
  dict(super(NeutronAPIDictWrapper, self).to_dict())`, `d['subnets']` is
  a list of strings so `d['subnets'] = [s.to_dict() for s in
  d['subnets']]` can only fail.
