You can use
   \once \override Script #'avoid-slur = #'outside d'8-.
the default setting for "'avoid-slur for articulations varies from 
articulation to articulation
(and is defined in the file scm/script.scm) and for staccato, the 
default setting is #'inside.

Ugly! Yet another problem with grace notes! Note that the problem 
remains the same even if you
remove the \once \override setting within the acciaccatura, i.e. the 
problem is that you begin the
Voice context with a grace note.
One possible workaround is to move the \voiceTwo command so it comes 
after the acciaccatura.
Another workaround is to do all settings corresponding to \voiceTwo using
\new Voice \with{
 \override Stem #'direction = #DOWN
 \override Slur #'direction = #DOWN
 ...
}{
       \acciaccatura {\once \override Stem #'direction = #up c'8}
   d'8[ ...

However, the list of property settings is farly large and unfortunately 
the syntax does not allow you
to do \new Voice \with{ \voiceTwo } {...}.
