If a revision is specified in a way that looks like a commit hash, Lix expects
that it actually is a commit hash. Unlike Git, Mercurial will fall back to
bookmarks, tags and branches with the specified name when a commit with the
specified hash does not exist. Previously, an assertion failure would be thrown
due to the resulting commit hash mismatch. Tell Mercurial to only take commit
hashes into account, whose non-existence is then handled gracefully.

When using the Mercurial fetcher on a local repository without explicitly
specifying a branch or revision, previously always the tip of the default
branch would be fetched. This is likely unexpected by the user, and
inconsistent with the Git fetcher as well as the dirty case. To reduce
surprises and restore consistency, fetch the currently checked out revision
instead.

The Mercurial fetcher previously used the revision number supplied by Mercurial
as its revision count. This is inappropriate, as the revision number is
incremented each time a change is added to the local repository, so also
changes only reachable from other heads will be counted. For the same reason,
it will also depend on whether such changes have been fetched before from the
same repository, introducing an impurity. Instead the revisions have to be
counted explicitly, similar to the Git fetcher.

I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests
- Concepts is harder to understand, the documentation makes a good
unit vs functional vs integration distinction, but when the
integration tests are just two subdirs within `tests/` this is not
clear.
- Source filtering in the `flake.nix` is more complex. We need to
filter out some of the dirs from `tests/`, rather than simply pick
the dirs we want and take all of them. This is a good sign the
structure of what we are trying to do is not matching the structure
of the files.
With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests
functional/
installer/
nixos/
```
