fix for MOSYNC-2873 ImagePickerTest crashes on Android if you check the "return image data with the event" option

- a fix in the runtime -> made sure that the bitmap exists and hasn't
already been recycled before recycling
- the main fix: the ImagePickerTest where the image placeholder was
being destroyed while the image was active (i.e. displayed)
Fixed Android build error after updating SDK tools to 22.0.1
