Resolve intent before launching from DashboardFragment.

Once dashboard tile is displayed, the underlying intent can be disabled.
We will eventually hide the item from UI, but there can be a brief
moment before we are able to hide it. So to prevent user click and
launch a non-exist intent, we will try to resolve it first before
launching anything.
