Fix the autoloader to enable local development

[datengraben]

This PR fixes #1200 (the composer autoloader issue) and enables the following:

• [x] execution of phpunit (from vendor/bin)
• [x] execution of phpcs (from vendor/bin)
• and hopefully any other composer invoked command

Problem

The ed-itsolutions/cmb2-field-ajax-search dependency registers itself in the autoloader.files directive very early. See: https://github.com/Ed-ITSolutions/cmb2-field-ajax-search/blob/18f11794eef0ac638041192f25311580f68ef90a/composer.json#L16

But it has no own autoloader or bootstrapping files, so it won't load wordpress definitions on its own.

So the plugin file depends on wordpress definitions do_action etc., which are not loaded at this moment. https://github.com/Ed-ITSolutions/cmb2-field-ajax-search/blob/18f11794eef0ac638041192f25311580f68ef90a/cmb2-field-ajax-search.php#L24

Because of this, the autoloading process of commonsbooking fails, but the autoload of any other plugin, that depends on it will fail too.

Solution

Since it seems to be no good style and also breaking the autoloader of other wordpress plugins (I testet it), I forked the 4 years inactivate cmb2-ajax-search module and removed the autoloader from our composer json (https://github.com/datengraben/cmb2-field-ajax-search/commit/887470a5cb9363a51d573bb8d49259435f519511) , added a require_once to our plugin initialization file (https://github.com/wielebenwir/commonsbooking/pull/1656/commits/46dea14bd057ccc517f0b85f107d7c7b38a32f4f).

@hansmorb ok jetzt habe ich doch eine Lösung gefunden. Ich habe es aber noch nicht bei uns im Staging getestet.
