TASK: Fix MySQL migration differences on fresh setup

[kdambekalns]

This eliminates some differences in the actual vs the expected DB setup in a fresh
Neos 8.3 installation.

Fixes #3118 (at least partly.)

Review instructions

doctrine:migrationgenerate should just say No changes detected after Neos has been set up.

Hu i must have lost track of this :D Should we still target 7.3 (last bugfix) or rather 8.3 to be safe?

[mhsdesign]

I changed the base branch once, but could you please rebase on 8.3 and check if the pr is still correct ^^

[kdambekalns]

Will check…

[kdambekalns]

With 8.3 this now gives me:

beach@95d7d5a35363:/application$ ./flow doctrine:migrationgenerate
No changes detected

[Sebobo]

Thx, did you check if Postgres is also affected?

[kdambekalns]

If only I could remember. Maybe? It probably needs to be updated yet again, anyway…

Current output with new Neos 8.3 is:

        $this->addSql('ALTER TABLE neos_contentrepository_domain_model_nodedata DROP INDEX IDX_CE6515692D45FE4D, ADD UNIQUE INDEX UNIQ_CE6515692D45FE4D (movedto)');
        $this->addSql('ALTER TABLE neos_media_domain_model_tag DROP FOREIGN KEY FK_CA4889693D8E604F');
        $this->addSql('ALTER TABLE neos_media_domain_model_tag ADD CONSTRAINT FK_CA4889693D8E604F FOREIGN KEY (parent) REFERENCES neos_media_domain_model_tag (persistence_object_identifier) ON DELETE SET NULL');

And after appling this PR:

./flow doctrine:migrationgenerate
No changes detected

@Sebobo Can we merge this anyways? If there are postgress issues we can handle that also in a dedicated PR.

This is open for almost two years now and I'd like to merge it to improve the mysql usage experience.

[Sebobo]

Yes sure, I mean the title also says mysql
