produce misleading warnings (when combining into chords)

This also happens with \partcombine in lilypond 2.15.x, but didn't in 2.14.

The problem only appears when the slurred notes are combined into chords  
(i.e. there are two notes in the resulting chord that start/end a slur).
I suppose it is due to the fact that EventChord handling has changed  
recently in a way that broke slur handling.

In particular, when part-combining into a chord (and only then) both notes  
of the chord have a slur event, which didn't cause problems previously.

Attached is a test case that I would add as a regression test.
