Map::getFacadeAccessor() returning new instance with each call to Map facade

[JFossey]

Thanks for a very helpful and time saving package.

I was trying to use a custom blueprint class by using Map::blueprintResolver(). This seemed to have no effect.

After a short investigation I discovered that because Map::getFacadeAccessor() is returning an object instance and Facades::resolveFacadeInstance($name) returns objects immediately without adding them to the $resolvedInstance static property.

The side effect to this that every call to the Map facade will resolve a new instance of Builder making the blueprintResolver() method un-usable.

So from my point of view if I understand everything correctly, to use the Map Facade as intended getFacadeAccessor() will need to return a object instance saved to a property in Connection or a Application container singleton.
