fix(schematics): ensure project "style" and "skipTests" options are respected

With angular/angular-cli@a12a4e0, the CLI made the
option naming consistent. Since the default schematic are therefore named differently, we need to update our logic
to work with the old option name and the new option name.

Fixes #15502
