title: Unexpected pipe 'ValuesPipe' imported by the module 'HomieModule'
body: <p>Im having problems while importing a Pipe with this setup:  I have a dashboard.Module which connects with Homie.Module and Services.Module via Dashboard-routing.Module </p>
  
  <p>This is my <strong>Dashboard.Module</strong></p>
  
  <pre><code>import { DashboardRoutingModule } from './dashboard-routing.module';    
  import { ValuesPipe } from './values-pipe.pipe';
  
  @NgModule({
    imports:      [ DashboardRoutingModule, CommonModule],
    providers:    [ HomieService, ServiceService ],
    declarations: [ DashboardComponent, ValuesPipe],
    exports: [ValuesPipe],
    bootstrap:    [ DashboardComponent ]
  })
  export class DashboardModule { }
  </code></pre>
  
  <p><strong>Homie.Module</strong></p>
  
  <pre><code>import { ValuesPipe } from './../values-pipe.pipe';
  
  @NgModule({
    imports: [
      CommonModule,
      HomieRoutingModule,
      FormsModule,
      Ng2SearchPipeModule,
      ValuesPipe
    ],
    declarations: [HomieListComponent, HomieDetailComponent]
  })
  export class HomieModule { }
  </code></pre>
  
  <p><strong>Service.Module</strong></p>
  
  <pre><code>import { ValuesPipe } from './../values-pipe.pipe';
  
  @NgModule({
    imports: [
      CommonModule,
      ServiceRoutingModule,
      FormsModule,
      Ng2SearchPipeModule,
      ValuesPipe
    ],
    declarations: [ServiceDetailComponent, ServiceListComponent]
  })
  export class ServiceModule { }
  </code></pre>
  
  <p><strong>Error</strong></p>
  
  <pre><code>core.es5.js:1020 ERROR Error: Uncaught (in promise): Error: Unexpected pipe 'ValuesPipe' imported by the module 'HomieModule'. Please add a @NgModule annotation.
  Error: Unexpected pipe 'ValuesPipe' imported by the module 'HomieModule'. Please add a @NgModule annotation.
  </code></pre>
  
  <p>When I declare my pipe in Homie and Service modules I get the error message: pipe declared in two modules.
  So thats why I moved my pipe to Dashboard.module which is the module that connects with both (Parent).  </p>
