    Regenerate context during targeting

    We are only doing a copy.copy() on context when we do target_cell(),
    which may mean we're sharing more across threads than we intend to.
    This makes that a full regeneration of the context (like we would
    do over RPC). This will necessarily dump the targeting, if already
    set, and any per-thread database context.
