Updating ItemInfoMatcher to work with java streams

Adding support for bulk removing items from a folder icon.
This fixes workspace item removal when a folder gets replaced
to an icon during the delete operation.

- Lets say user has a folder with the same app twice.
- User disables that app.
- Launcher removes all shorcuts of that app

However, because we call "replaceFolderWithFinalItem" during
this removal, we end up creating a new shortcut that does
not get tracked by the removal, so the user is left with
an enabled icon of the disabled app.
