Migration generator shows wrong summary

[zimt28]

Example, the generator actually created 5 files:

* creating priv/repo/tenant_migrations/20210727125616_migrate_resources2.exs
No changes detected, so no migrations or snapshots have been created.

Closing this, as the output is actually correct: The first line refers to tenant migrations while the second one refers to public migrations. Some headings and an empty line between those might be nice though :)

Improved the formatting/information contained in the output there, agreed that it was confusing otherwise :D
