Two bits of cleanup In UIViewLazyList (#1659)

- Removing call to set contentView.translatesAutoresizingMaskIntoConstraints to false, because this is not supported by iOS, and yields the following warning:

"Changing the translatesAutoresizingMaskIntoConstraints property of the contentView of a UITableViewCell is not supported and will result in undefined behavior, as this property is managed by the owning UITableViewCell"

- Adding call to removeAllSubviews within prepareForReuse
