Remove duplicates with overwrite-migrations flag

[ghostwriter]

Currently:

If you run php artisan blueprint:build more than once, without the -m|--overwrite-migrations flag, Blueprint will generate duplicate migrations with different timestamps.

If you then run php artisan blueprint:build -m or php artisan blueprint:build --overwrite-migrations, Blueprint will overwrite ONLY the first migration file it finds. All other duplicate migrations with different timestamps will still exist.

PR:

1. Running php artisan blueprint:build

   • Blueprint will still generate duplicate migrations with different timestamps with php artisan blueprint:build (for comparison,testing, etc.)

2. Running php artisan blueprint:build -m or php artisan blueprint:build --overwrite-migrations

   • Blueprint will update the oldest existing migration file.
   • Removes all other duplicate migrations with different timestamps.
   • Reports deleted files
     

• resolves Option to overwrite duplicate migration files #370
