Cabal passes `--source-*` options to Haddock even when new hyperlinked-sources backend is in use

**Describe the bug**
Run `cabal haddock` with building of hyperlinked sources enabled. `haddock` will rightly complain that:
```
Warning: --source-* options are ignored when --hyperlinked-source is enabled.
```

**To Reproduce**
Steps to reproduce the behavior:

```
$ cabal unpack acme-box
$ cd acme-box-*
$ cat > cabal.project <

Reproduce with the acme-box example, a cabal.project setting haddock-hyperlink-source: True, and cabal haddock. Start at the cabal haddock command's Haddock option handling; done means --source-* options are omitted when hyperlinked sources are enabled and the warning no longer appears.
