Always call callback when taking picture

[milosfec]

Issue description

When calling CameraHelper.takePicture(...), there are several cases when error is not reported to the provided callback.

Use case

Applications shows a dialog while taking picture is in progress. This dialog is dismissed when picture is taken, or replaced with a closable error dialog when error occurs. When camera get disconnected right before we call takePicture(), callback is not called at all and the dialog will never be dismissed.

Solution

Handle every cases when taking picture and call callback.onError() when getting image is not possible or failed.

Notes

The fix touches just one internal interface ICameraRendererHolder.java, so it brings no braking changes to any user of the library.
