[REV] re-enable the multiple calls of initialize_sys_path
[REV] re-enable the multiple calls of initialize_sys_path

Some of the implicit side-effects got missed, namely that under some conditions
(e.g. using an odoo subcommand) `initialize_sys_path` can be called before the
config has been loaded at all, resulting in the first call not properly setting
up things, and one of the subsequent calls fixing things up.

Since this breaks workflows right now, quickly fix it, we'll re-investigate
how to fixup the entire thing in order to restrict & enforce a single call.

closes odoo/odoo#45844
