[MovieApp] Add key to image components inside of MovieCell.

[christopherdro]

Resolves #89

test plan: open movies app, search for various movie titles, ensure that the images match the titles

[brentvatne]

looks good to me

It would probably be better to add the key to the whole cell:

react-native/Examples/Movies/SearchScreen.js

Line 264 in ccd9f00

<MovieCell

Mind changing it to that?

[christopherdro]

That's actually what my first attempt at resolving the issue was.

However, I was still able to reproduce the issue.

Could this be a bug with the Image component?

[sophiebits]

That doesn't make sense to me.

[sophiebits]

If the row's key changes, all of its descendants including the Image will be recreated.

[christopherdro]

Hmm, I must've of overlooked something then.
I just tested a decent amount of times with setting the key on the whole cell.

Will cleanup and push. Thanks

[christopherdro]

Sorry for the problems.
Created a new PR with the proper changes.
