Install missing and outdated roles before running the playbook

Pulling a playbook update which adds roles or bumps their versions
required running `just roles` before the playbook could use them.
Otherwise, the run failed on a missing role or used an outdated one.

`just run`, and so `just install-all`, `just setup-all` and the other
recipes based on it, as well as `just register-user`, now first install
missing and outdated roles, the same way `just roles` does: roles with
local changes are kept (with a warning), as are symlinked roles and
roles containing a `.git` directory. When all roles are up to date,
nothing is downloaded and nothing is printed.

The same change in mash-playbook:
