bain: Fix install attempts causing LO lock warning RRR

Not sure this is the right approach, I'm only semi-familiar with LO code
and not at all familiar with BAIN code. Note that I changed defaults for
the ModInfos.refreshLoadOrder parameters, two places used True for
them, one explicitly specified both and none used False.

Under # 309 <--- RRR
