ChangeDetectionStrategy.OnPush missing in a few components

[vlin59]

I'm on angular: 6.0.0 and angular_components: 1.0.1.

Using the MaterialSelectComponent gives this compile-time warning when the parent uses the OnPush Change Detection Strategy.

"MaterialSelectComponent" doesn't use "ChangeDetectionStrategy.OnPush", but is used by a component that does.

ReorderListComponent and MaterialSelectSearchboxComponent appears to also require it.

I haven't come across anything else in my codebase but more could be missing.

Fixed in the latest, Angular-7-compatible ngcomponents
