ENYO-373: Pass parameter to prevent adding moon.ContainerInitializer to roots.

### Issue
When initializing a select set of controls for performance reasons, the container for these controls is initialized as the Spotlight root, which causes subsequent Spotlight issues when controls do not have a spottable parent and instead use the Spotlight root.

### Fix
Instead of making a quick patch to Spotlight (a full solution here will require some more design), we made a change to `enyo.Control.renderInto` (https://github.com/enyojs/enyo/pull/906) to accept a boolean parameter to prevent adding of a control to the view roots. Here, we pass true for `moon.ContainerInitializer`. Thanks to @ryanjduffy for the initial fix.

### Notes
This PR depends on https://github.com/enyojs/enyo/pull/906. This also needs to be cherry-picked into the `branch-2.5.2-pre.4` branch.
