Describe the bug

Vanilla RecipeTypes are created in AE2 using InitRecipeTypes.
They use a deferred registration, so they are statically created and call appeng.init.InitRecipeTypes#register, and then later get registered when RegisterEvent is fired for Registries.RECIPE_TYPE and appeng.init.InitRecipeTypes#init is called.

Unfortunately, if a RecipeType's parent class is not called before the registration stage, the RecipeType will call appeng.init.InitRecipeTypes#register after appeng.init.InitRecipeTypes#init has already run, and it will never get registered with the vanilla system.

How to reproduce the bug

Put a breakpoint in appeng.init.InitRecipeTypes#init
and see if all the recipe types are present.
The ones I know of are

EntropyRecipe.TYPE;
ChargerRecipe.TYPE;
InscriberRecipe.TYPE;
MatterCannonAmmo.TYPE;
TransformRecipe.TYPE;

In my experience, MatterCannonAmmo.TYPE and EntropyRecipe.TYPE are missing from the registration.

Expected behavior

All AE2 recipe types should be registered with the vanilla system when the registry event is fired.
