Android saves to file but not camera roll #52

First off, thank you for taking the time to write this plugin.

I have it working as intended on iOS but on my Android version (Lollipop), it saves the image as a file to the Pictures folder, but it does not show up in the camera roll. I can get it displayed if I open up "Photos" and choose "Device Folders" as the source. Additionally, the success callback fires but the return value is empty so I do not have a path.

The same thing happens on your demo app here: https://build.phonegap.com/apps/946650/share

I should mention that I'm using PhoneGap Build.
