Improve sync info (#692)

- Fixed an edge case where disconnecting and then reconnecting would
retain outdated info
- Fixed an issue where new patches wouldn't immediately update the
change info text
- Removed extraneous changes count info, as it was not useful and could
be checked in the visualizer anyway
- Added warning info for when some changes fail to apply
- Updates timestamp of last sync even if patch was empty, to have a more
accurate signal on Rojo's uptime
