UserBundle: Allow adding/removing ports

Browse source 
Clean up internal API confusion
- can_add_channels_proxy () -- checks presence of io
- can_add_channel_proxy () -- checks io->can_add_port()

UserBundle don't have a PortGroup::_bundle reference
that can be used to lookup the IO via io_from_bundle().

While BundleEditorMatrix::can_add_channels_proxy() was overriden
to allow adding I/Os, can_add_channel_proxy() later prevented that.

This further prevents removing the last port, preventing empty bundles.
