Implement dry run version of the script

[ka8725]

Create a mechanism that allows to roll back the phantom migrations.

Ideas on how to implement it (can be implemented both):

1. Add an option to the command line: rake db:rollback_branches --dry-run
2. Via env var. Apply dry run if ACTUAL_DB_SCHEMA_ROLLBACK_BRANCHES_DRY_RUN=true

The dry run should not roll back any migrations but rather output the phantom migrations list.

Prefer the same output format in the output as in the following Rails' task:

rails db:migrate:status

 Status   Migration ID    Migration Name
