Current behavior

ng add will fail if assets/svg folder not exists

Expected behavior

ng add should not run npm run generate-icons if there is no svg folder / shouldn't run at all / console log instructions with next steps

Minimal reproduction of the problem with instructions

ng new svg-icons-test
ng add @ngneat/svg-icon

Output:


ng add @ngneat/svg-icon
