Using a class reflector based on composer.json won't load interfaces

[WyriHaximus]

Been working on a composer plugin that runs before dumping the autoloader so the normal autoloader isn't available. With some advise from @asgrim and @Ocramius they suggested the following:

(new ClassReflector((new MakeLocatorForComposerJson())(dirname($vendorDir), (new BetterReflection())->astLocator())))->getAllClasses()

To get all classes and iterate over them so see which ones implement a specific interface. Now when doing so I'm getting errors about missing interfaces:

"Psr\EventDispatcher\ListenerProviderInterface" could not be found in the located source
"Composer\Plugin\PluginInterface" could not be found in the located source
"Psr\EventDispatcher\ListenerProviderInterface" could not be found in the located source
"Psr\EventDispatcher\EventDispatcherInterface" could not be found in the located source
"Psr\Log\LoggerInterface" could not be found in the located source

"Composer\Plugin\PluginInterface" could not be found in the located source

This one seems like a valid/expected crash, since PluginInterface is only available during composer command execution, or when requiring composer/composer.

"Psr\EventDispatcher\ListenerProviderInterface" could not be found in the located source

Seems strictly relate with #551

Yup, especially since I've been testing with a composer run-script, will test it with a composer install/update to see if it works as intended.

Doh 🤦‍♀️ . Doing these kind of things tends to show you all kinds of shit in all kinds of packages 😂 . Will take it up inside the FIG

Got it to work with a goto using MakeLocatorForComposerJsonAndInstalledJson, can drop the goto when doctrine/coding-standard#176 gets merged and tagged 🎉 . Turns out you need the installed to get the rest of your dependencies 😂 .
