snapshot: Fix showing unsupported message on non-btrfs filesystems

Browse Source 
This is a regression from commit 9b6774f279e2c8af588609c2413aa9804fd48cfa. 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.

Tests:

- On non-btrfs filesystem, snapshots view is shown as expected.

- On ext4 filesystem, a message that snapshots are not supported is shown.
