Clean up unused Tags, LocSubjects, and Collections

Browse source 
On `Ebook::Save()` and `Ebook::Delete()`, remove any unreferenced `Tag`,
`LocSubject`, and `Collection` records. These are analogous to these lines in
`Ebook::Create()`:

```
$this->CreateTags();
$this->CreateLocSubjects();
$this->CreateCollections();
```

`EbookPlaceholder`s can't have `Tags` or `LocSubjects` at the moment, but other
mistakes in production that are later corrected could leave unused `Tags` and
`LocSubjects`.
