Remove the refresh step from CAgg migration

We're facing some weird `portal snapshot` issues running the
`refresh_continuous_aggregate` procedure called from other procedures.

Fixed it by ignoring the Refresh Continuous Aggregate step from the
`cagg_migrate` and warning users to run it manually after the execution.

Fixes #4913
