[PATCH] [minimap] Fix minimap-kill when there is no timer object

[emacs-devel]

From: Adam Spiers <emacs@adamspiers.org>

Occasionally minimap-timer-object can be nil when minimap-killer
is triggered.  In this case, the following error is triggered:

    cancel-timer: Wrong type argument: timerp, nil

So defensively check whether there is a timer to cancel before trying
to cancel it.
