title: Get store item in Effect
body: <p>I have a small Effect and I need to get the action data (nanoId) and I need to select data with this nanoId in store:</p>
  <pre><code>  @Effect()
    syncObj$ = this.actions$.pipe(
      ofType(ObjActions.Actions.SYNC_NEW_OBJ),
      mergeMap(({nanoId, obj}) =&gt; {
        this.store.pipe(select(getObjByNanoId(nanoId), first())).subscribe(eObj =&gt; {
          // return [] &lt;-- error if I try to return pipe result here and remove return below
        })
        return [] // &lt;-- this is below return
      }
      )
    );
  </code></pre>
  <p>I thought of <code>withLatestFrom()</code> but it needs an additional pipe, as I understand.
  My goal is to catch an object and nanoId from action, then select an object with nanoId in store (eOnj) and compare some of it's fields. Thanks!</p>
