make db-migrate confusingly prints "Schedule the propagations"

[zenovich]

After migrations applying, instead of printing that it runs propagations, make db-migrate prints "Schedule the propagations" and it's not obvious if it runs them. Actually it does, but the message is confusing.

The 'db-migrate' command should clearly print that it runs the propagations and run them as it did before this change:

The same issue is related to 'db-recompute' and 'propagation' commands
