fix(@schematics/angular): findModuleFromOptions not handling properly different casing in name

At the moment users can have various casing and seperatirs in paths, we should not always dasherize the name when resolving modules.

As for example when providing something like:

```
/module/SubModule/feature
```

It won't be able to resolve the modules properly as `sub-module` does't exist.

This PR also updates the test for underscore as previously it was not properly testing this usercase, since the formatter was used on name and not th path.

Fixes #13714
