Warning about "The feature name \"${featureName}\" does not exist" creates a lot of noise in tests

[alex-okrushko]

When running tests this message happens a lot:

platform/modules/store/src/selector.ts

Lines 618 to 624 in 379ddfb

	`@ngrx/store: The feature name \"${featureName}\" does ` +
	'not exist in the state, therefore createFeatureSelector ' +
	'cannot access it. Be sure it is imported in a loaded module ' +
	`using StoreModule.forRoot('${featureName}', ...) or ` +
	`StoreModule.forFeature('${featureName}', ...). If the default ` +
	'state is intended to be undefined, as is the case with router ' +
	'state, this development-only warning message can be ignored.'
