/**
 * Finds the most appropriate model to use for the given target locale list.
 *
 * The basic logic is: we ignore all models that don't support any of the target locales. For
 * the remaining candidates, we take the update model unless its version number is lower than
 * the factory version. It's assumed that factory models do not have overlapping locale ranges
 * and conflict resolution between these models hence doesn't matter.
