Charles Lyding 5ce621e371 fix(@angular-devkit/schematics): resolve external schematics from requesting collection
This change first attempts to resolve a schematic referenced via the external schematic rule from the requesting schematic collection.  This allows schematic packages that are direct dependencies of another schematic package to be used with the external schematic rule without manual package resolution code within the schematic.
