fix(core): normalize paths in ng cli adapter when finding matching files

[leosvelperez]

Current Behavior

Running an Angular Schematic on Windows might fail due to mismatching path formats when trying to find a matching file change.

Expected Behavior

The Ng CLI adapter layer should make sure paths being compared are normalized so their formats are the same and they can match as expected.
