caches: move the 'updating the branch cache' message in 'updatecaches'

We are about to remove the branchmap cache update in changegroup application.
There is a debug message alongside this update that we do not want to loose. We
move the message beforehand to simplify the test update in the next changeset.
The message move is quite noisy and isolating that noise is useful.

Most tests update are just line reordering since the message is issued at a
later point during the transaction.

After this changes, the message is displayed in more case since local commit
creation also issue it.

'''browse command output with an external pager (DEPRECATED)

Forcibly enable paging for individual commands that don't typically
request pagination with the attend-<command> option. This setting
takes precedence over ignore options and defaults::

  [pager]
  attend-cat = false
