isMockOf

isMockOf helps when we want to use ng-mocks tools for rendering, but typescript does not recognize an instance as a mock object.

We need this when we get an error like:

Property '__render' does not exist on type <class>

Property '__hide' does not exist on type <class>

// checks whether `instance` is
// an instance of `MockedModule<SomeClass>`
if (isMockOf(instance, SomeClass, 'm')) {
  // yes it is
}

// checks whether `instance` is
// an instance of `MockedComponent<SomeClass>`
if (isMockOf(instance, SomeClass, 'c')) {
  // yes it is
}

if (isMockOf(instance, SomeClass, 'd')) {
