bar: call refresh() after all modules have been loaded

This also means that modules do *not* have to call bar->refresh() just
before/after calling module_signal_ready().

As long as the module's initial state has been correctly/completely
set up before it calls module_signal_ready(), the module *only* has to
call bar->refresh() when it's state changes.
