Mike Grabowski	4555b06ffd	Fix broken releases script Summary: Fails on my machine due to fact that `replace` returns an instance of a String, rather than an instance of ShellString (that includes `to` on its prototype). Solution is to use an explicit `writeFileSync`. You can see that change in the wild on 0.50-stable branch.

Janic DuplessisandJames Ide	776bd34eb3	Validate that JS and Native code versions match for RN releases Summary: Basic implementation of the proposal in #15271 Note that this should not affect facebook internally since they are not using OSS releases. Points to consider: - How strict should the version match be, right now I just match exact versions. - Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help. - Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning. - Should the check and native modules be __DEV__ only? Test plan Tested that it works when version match and that it redscreens when versions don't before getting other errors on Android and iOS.

Ben RothandJames Ide	6d64892c8a	Fix crash when trying to load photo library assets with nil image url Summary: This avoids a crash when we try to load a PHAsset with nil image url. Specifically, the following condition evaluates to true when `imageURL` is nil: ```objc if ([imageURL.scheme caseInsensitiveCompare:@"assets-library"] == NSOrderedSame) { assetID = [imageURL absoluteString]; results = [PHAsset fetchAssetsWithALAssetURLs:@[imageURL] options:nil]; } ``` The crash will be "attempt to insert nil object from objects[0]" when we build the `@[imageURL]` array literal. We've seen this emerge as a very common crash among Expo users, so I wanted to at least provide a clear error message instead of terminating the app. Load an image from the photo library with a nil request url.
