move mem::uninitialized deprecation back by 1 release, to 1.39

As per discussion at https://github.com/rust-lang/rust/issues/53491#issuecomment-509271182. Three releases also agrees with the precedent from `trim_left/right`. Three releases means that even nightly users (including rustc itself) get a full cycle from when the announcement is made in the stable release to when nightly starts to warn.
