Static class methods receive the prototype as the target and not the class

[cneuwirt]

I have a class that looks like

class CustomInstance { static uniqueEmail(email, @type(Database) database) { if (email != null && database.hasEmail(email)) { return ${email} is already taken; }
} }

function type(target, propertyKey, parameterIndex) { ... }

The first argument (target) passed to the type decorator for static method uniqueEmail receives the CustomerInstance.prototype and not the CustomerInstance class itself. This breaks managing the metadata
