Execute FK queries at the end

[WilliamFalci]

Those changes move the FK's queries outside the creation queries and go to execute all them at the end of all other queries

Thank you for the PR, please do the following to proceed:

1. squash both commits
2. create a more informative commit message
3. utlize the "Resolves issue xxx" phrasing GH can use to link to the issue describing what this fixes
4. address comments in the code

Thank you, looking forward to your changes.

Hey @WilliamFalci ,
this version is not working, it is showing this message when executing the shell command mysql-schema-diff:

Use of uninitialized value in unpack at /usr/share/perl5/MySQL/Diff/Table.pm line 246.

and it is generating a SQL not completely sorted ("CONSTRAINT films_selected_trailer_pack_dcfafea4_fk_trailer_packs_id" should be after "CREATE TABLE trailer_packs", there is a cyclic dependency, the table trailer_packs references the table films and the table films references the table trailer_packs):

ALTER TABLE films ADD CONSTRAINT films_selected_trailer_pack_dcfafea4_fk_trailer_packs_id FOREIGN KEY (selected_trailer_pack) REFERENCES trailer_packs (id);

CREATE TABLE trailer_packs (
  id int NOT NULL AUTO_INCREMENT,
  notes longtext COLLATE utf8mb4_general_ci NOT NULL,
  film int NOT NULL,
  printid int DEFAULT NULL,
  PRIMARY KEY (id),
  KEY trailer_packs_film_3f48c68a_fk_films_code (film)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

ALTER TABLE trailer_packs ADD CONSTRAINT trailer_packs_film_3f48c68a_fk_films_code FOREIGN KEY (film) REFERENCES films (code);

The SQL above creates the error:

Failed to open the referenced table 'trailer_packs'

@diegobill Hello! Sincerally I stopped to write in PHP many years ago and my current stack is node/typescript (primary), I remember I ended to make this: https://github.com/WilliamFalci/_mysqlDiff and when I did was working pretty good.

If you not find a solution I will try to help you to figure out the solution, but I have no effort to develop more in PHP.
