Remove UL "" initialization from init.h.

mutt_init() calls mutt_set_default() followed by
mutt_restore_default().  The mutt_restore_default() calls
mutt_str_replace(), which translates "" into 0.

Therefore assigning "" to the option->init field simply wastes space
and (incorrectly) implies the option->data will be non-NULL by default.
