Updated misc in Contextual Settings Homepage

method.
- Removed Storage card from createStaticCards method because it does not
belong to default category.
- Changed the parameter type of setSliceUri from String to Uri in ContextualCard.
- Added StorageSlice and DeviceInfoSlice to the contextual card
provider.
- Fixed test cases related to these changes.
