* CNANDContentManager does things that are absolutely useless. In
particular, it parses the ticket, the TMD, reads contents, etc.
when we only need to remove the title directory.
* This means it will fail if the ticket cannot be found, when that
should not be the case.
* This also obviously caused DeleteTitle to be incredibly inefficient.
* We are already removing the title directory later in the function,
as CNANDContentManager does not even delete titles correctly.
DeleteTitle != DeleteTitleContents.
