Fixes for returning to the compact editor from the expanded one

* Don't abort the save even if there are no unsaved changed
  when returning the compact from the full editor
* No need to pass the material palette on insert intents.
  It does, however, need to be passed back to the compact
  editor when editing an existing contact w/o a picture.
* Fix returning to the compact editor repeatedly by
  removing the Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET
  on compact editor intents.
* Updated StructuredNameEditorView#getDisplayName to fall
  back to the display name directly from the ValuesDelta.
  This is required when the name is passed to the
  contact editor, and the user does not change it, in which
  case it will not be written to the underlying data
  structure, and thus not passed subsequent expantions.
