configure_per_game: Initialize tabs after loading custom configuration

Changes tab initialization to happen after the configuration is loaded,
which means that it no longer happens as member initializers in the
ConfigurePerGame constructor. Removes the cluster of
??_tab->SetConfiguration's that I added earlier to get around this issue
initially.

Fixes a regression in #6774
