ngMocks.guts() does not create mocks for declarables exported from other modules

See original GitHub issue

ngMocks.guts() does not create mocks for declarables exported from other modules.

This happens when a module is imported that exports a declarable (a component, directive or pipe) that it does not declare in itself.

This leads to the following error: Error: Can’t export pipe MockOfTranslatePipe from MockOfMyTranslateModule as it was neither declared nor imported!

Reproduction steps:

@NgModule({
  declarations : [
    AppComponent
  ],
  imports : [
    BrowserModule,
    MyTranslateModule // <- This module exports TranslatePipe but does not declare it!
  ],
  providers : [],
  bootstrap : [AppComponent]
})
export class AppModule {
}

@NgModule({
    imports: [TranslateModule],
    declarations: [],  // <- TranslatePipe is NOT declared because it is imported from TranslateModule
    exports: [TranslatePipe],
})
export class MyTranslateModule {}```
