Fixes pick image from Picasa on Android < 3.0

More details: https://code.google.com/p/android/issues/detail?id=21234#c17

I tested it on the Nexus One (Android 2.3.6).

VideoChooserManager.processVideoFromGallery should probably be changed to handle Picasa videos on older Android < 3.0 also.

Since both methods do the same, perhaps that code could be refactored.
