Current behavior

The option --lint-fix is not accepted by the schematic @ngxs/schematics:store.

Expected behavior

Allow the files generated by schematics to be automatically linted similar to @ng/cli.

Minimal reproduction of the problem with instructions

Run these commands to see difference:

ng g @ngxs/schematics:store --name=test --path=app/store --lint-fix=true
ng g c test --lint-fix=true

What is the motivation / use case for changing the behavior?

After generated files are checked in, the linting by IDE (using project configuration) causes additional changes in subsequent commits.
