Show the extra separators below UITableView

[davidperrenoud]

By default on iOS, UITableView shows extra separators in the empty place below the cells:

As RNTableView is always initialising tableFooterView, these separators aren't shown. Could we initialise the footer only when we actually need?

At the moment, you can disable the footer by commenting this line:

_tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

And this line:

_tableView.tableFooterView = view;
