Update charm-refresh to v3.0.0.3 (#1008)

Fixes UX bug: canonical/charm-refresh@80c7d80

Ideally, this should be included before the first stable release (so that if the user accidentally refreshes to the charm revision with the first stable release from a different track, they see the correct error message & so that the leader + highest number unit do not go into error state). However, it's not essential to include this in the first stable release.
