UIVideoPlayer-ios.mm regression fix. (#20368)

dave-ori · minggo · commit 796e09f4641e · 2019-11-23T09:57:46.000+08:00
[UIVideoViewWrapperIos clean] shouldn't reset _videoPlayer pointer,
since it is called in setUrl method and leaves instance in invalid
state. Subsequent calls to play, pause, etc. end up with crash.
