branchcache: cleanup the final key generation after update

A lot of duplicated work seemed to be done, as we already update the tiprev and
tipnode when needed right before. So we simplify that part to focus on the
filtered hash.

See inline comment for details.

These changes affect newly created repositories (or new clones) done with
Mercurial 6.3.

== New Experimental Features ==

== Bug Fixes ==

 * shelve: demonstrate that the state is different across platforms (issue6735)
 * shelve: in test for trailing whitespace, strip commit (issue6735)
 * shelve: remove strip and rely on prior state (issue6735)
 * tests: fix http-bad-server expected errors for python 3.10 (issue6643)
 * status: let `--no-copies` override `ui.statuscopies`
 * releasenotes: use re.MULTILINE mode when checking admonitions
 * rhg: fallback to slow path on invalid patterns in hgignore
 * Fix a bunch of leftover str/bytes issues from Python 3 migration

 * lfs: avoid closing connections when the worker doesn't fork
 * dirstate-v2: update constant that wasn't kept in sync
 * dirstate-v2: fix edge case where entries aren't sorted

== Backwards Compatibility Changes ==

 * chg worker processes will now correctly load per-repository configuration
   when given a both a relative `--repository` path and an alternate working
   directory via `--cwd`. A side-effect of this change is that these workers
   will now return an error if hg cannot find the current working directory,
   even when a different directory is specified via `--cwd`.
