msgviewer: cleanup PartSwitcher on :toggle-headers

Browse source 
Cleanup existing PartSwitcher before recreating a new one when command
:toggle-headers is executed, ensuring existing part pagers are cleaned
up.  This fixes a leak in pager processes when :toggle-headers is
executed repeatedly without closing the message.
