DolphinWX: Fix sorting games by custom titles

The custom title reading code is moved so that custom titles are
returned by GameListItem::GetName(). The comparison code is changed
to use GetName() instead of GetName(DiscIO::IVolume::ELanguage).

GetName(DiscIO::IVolume::ELanguage) must not return custom titles,
because netplay relies on it returning the same name for all players.
