Hi,
We have two issues here:
1. mdraid stuff is always included in initrd even system isn't on raid( ubuntu specific).
2. grow continue service is not restarted after switch root( to be fixed in upstream)

First one should be detected and managed in ubuntu installer. This is how it is done in other distributions. It will hide second problem when system is not on raid.
Initial ram disk should be minimal as possible, in this case md stuff is unnecessary.

As Pawel wrote reshape is managed by mdadm-grow-continue@.service or fork which is started by mdadm (if needed) as a last step of raid assembly. If it is started in initrd then it is not restarted after switch root because raid assemblation is already done. No fix for today- work in progress.

Please look into first one. I think that it is not a mdadm defect now, new launchpad is needed?
I will notify this lp when fix for second defect appears.

Thanks
Mariusz
