Possible bug: avoid-slur and TrillSpanners

[Knute Snortum]

 In this example...

%%% Start
\version "2.19.81"
\language "english"

{
  \override TrillSpanner.avoid-slur = #'inside
  \override TrillSpanner.outside-staff-priority = ##f
  c''1( | c''2. \startTrillSpan c''4 \stopTrillSpan | c''1) |
}
%%% End

...the slur doesn't avoid the trill spanner.
