Bottom edge tweaks

• Hide navigationbar only when the recent view is fully shown to reduce screen activities/animations when switching to the last tab (short swipe)
• Enabled immediateRecognition in the bottom edge handler to avoid scrolling webviews when swiping from the bottom
• Removed the close button from the navigation bar
• Fixed animation when doing a short swipe for switching to the last tab. Previous animation restarts the position from the bottom of the screen instead of continuing from the swipe/drag. It also previously does not reach the top and jumps at some point.
