Docker image not resuming when stopped.

[jgimeno]

Type:

Looks like for some reason an active node, if stopped cannot resume.

If it's an issue, how can we reproduce it?:

Run the docker image and let it sync, once sync stop it. And start it again and check logs.

Affected servers or services:

At least testnet

Priority:

Medium

This is caused by inconsistent state after reorg panic.
As far as #788 is merged, could you recheck full sync on currect dev branch?
