Fix Image Backgrounds crashing media views (#20)

- Removed comments from the BG hook as I decided I'm not going to do this
- Ensures that the length of subviews is at least 3 so that it does not into the negatives (2-3=-1 and so on). This would cause a native crash when trying to open a Media/Image view because the amount of subviews there is less than 3, meaning that when the Image bg subview is inserted it tries to insert it into a negative index.

-	// ! THIS PATCH IS TEMPORARY !
-	// for the time being this is done in the native side because it is extremely buggy on the js side
-	// for documentation purposes, the following issues are occuring with the current way that i am doing it on the js side (patch the common component that loads a linear gradient behind the chat area)
-	// 1. background is not transparent when using regular dark/light and not client themes
-	// 2. background does not apply on tabsv2
-	// 3. chat area is not interactive at all (unscrollable and chatinput is dead)
-	// 4. toggling between chat area and member view triggers fast flashing of the image
-	// 5. image is not positioned properly some of the time

-	// once i figure out how to properly do this on the js side (preferrably not patching View.render too) i will remove this implementation and do the proper js implementation.
