snapshot: Fix showing unsupported message on non-btrfs filesystems
This is a regression from commit 9b6774f2. When change the view to use AppView, the condition to check for non-btrfs filesystems and show an unsupported message instead of the actual view was accidentally removed. Restore the check and show a different view when on non-btrfs filesystems.
Fixes: #2268 (closed).
Tests:
-
On non-btrfs filesystem, snapshots view is shown as expected.
-
On ext4 filesystem, a message that snapshots are not supported is shown.
