Fix memory leak on BigImageViewer (#1067)
Leak found using LeakCanary. Steps:
1. Enable the LeakCanary dependency.
1. Open the app.
1. Open any post image, and go back.
According to `Piasy/BigImageViewer` documentation,
[Initialize section](https://github.com/Piasy/BigImageViewer/blob/9cc045e8146dc8833a487576745f17158bae4a4a/README.md#initialize),
the app context must be used to avoid memory leaks.
