Fix environment access in PackageInfo

An Environment's organization includes only the classes declared in the environment, not the imported classes. So use #at: to find the declared classes. This makes a difference if, though imports from other environments, a declared class gets hidden by a "foreign" class.

Also make sure to really look up in the organization of the current environment, so you can properly find classes and traits in other environments. Previously it would not have found classes in categories that do not exist in the default environment.
