Failing action unit test without creators from NgRx schematic

[walrus95]

When I use the action schematic to generate an action unit test with creators, I get a passing unit test. However, when I use the action schematic to generate an action unit test without creators, I get a failing unit test.

##Minimal reproduction of the bug/regression with instructions:

You get a failing spec when not using creators:

$ ng g @ngrx/schematics:action Add --project=counter --spec
$ npm test

ERROR in src/app/add.actions.spec.ts:1:10 - error TS2305: Module '"C:/Users/walrus95/proj/counter/src/app/add.actions"' has no exported member 'Add'.
1 import { Add } from './add.actions';

However, you get a passing spec when using creators:

$ ng g @ngrx/schematics:action Add --project=counter --spec --creators
$ npm test
TOTAL: 3 SUCCESS

Expected behavior:

I would expect my newly created test to always be passing regardless of the use of creators, but at the very least it should be consistent.

Versions of NgRx, Angular, Node, affected browser(s) and operating system(s):

NgRx 8, Angular 8, Node 10.16.0
