Minimise the time Vminibuffer_list is in an inconsistent state (src/minibuf.c)

Browse Source 
src/minibuf.c (get_minibuffer): Move the XSETCAR which writes the new
minibuffer into Vminibuffer_list to immediately after the MB's creation, so
that the list is in a consistent state before calling fundamental-mode or
minibuffer-inactive-mode.
