[Bug] Swipeview in Listview alters Listview Item Margin functionality on Android

[cbradbaer]

Description - With the use of the Swipeview in a Listview, there is no spacing between listivew items. Even if a Margin is specified in the Viewcell contents.

Steps to Reproduce

1. Create Listview with viewcell contents of a Grid. Give the grid a Margin of 15 which should create a 15 pixel space on all sides of the grid so that there will be a 30 pixel (15 pixel * 2) space between listview items
2. Run app to verify and verify correct spacing between listview items.
3. Now add a Swipeview to the listview and rerun the app.
4. The spacing will be gone and each listview item will be edge to edge. Instead, the spacing occurs like a Padding inside the Grid, growing the size of the grid to fill the space.
