Can't drop old tables if `Migrations.legacyTables` is set as command is not loaded

[LordSimal]

After executing bin/cake migrations upgrade the following info is displayed:

Upgrade complete!

Next steps:
  1. Set 'Migrations' => ['legacyTables' => false] in your config
  2. Test your application
  3. Optionally drop the empty phinxlog tables (re-run `bin/cake migrations upgrade --drop-tables`)

this is a bit misleading as bin/cake migrations upgrade --drop-table won't work with that config option set due to this if statement.

I'd remove the first step here completely and only show it after the old tables are dropped.

Thats a good idea. Switching the order actually should also already help. Those are numbered tasks.
