Remove sub-text from slice builder

We would like to remove all sub-text from Settings Search. But slice
view does not support API to configure the sub-text visibility.
Therefore, the only way is to remove the sub-text from slices directly.

Since Settings slices are also invoked by other apps, we can not
directly remove the sub-text.

Finally, we decide to check the caller's uid. If it comes from Settings
Search, we will return the slice without the sub-text.
