Avoid scheduling spurious completion updates

Browse Source 
Instead of setting `_ignore_change` to `True` before calling
`_change_completed_part` we just stop `_cmd` from emitting
`update_completion`.

This has the nice side-effect that when writing a complete command
`_ignore_change` was set to `True` regardless, and thus hitting space
would not update the completion view.

Now, hitting space will (as always) schedule a completion update that
now will not be incorrectly ignored
