When a setting is injected to homepage, we now allow the setting
provider customize the background color for its icon.
If no custom bg color is provided, we fallback to existing behavior.
This behavior is only needed in homepage, because we don't have any
tinting logic in other pages so external setting providers can just
provide arbitrary icon.

This allows Settings to test against the latest framework changes.
Also replaced TestConfig with traditional robolectric.properties.

If a homepage tile is injected from external packages, we can't
control what their icons look like, so we put a generic blue circular
background to make it consistent with the other icons.
