musicxml2ly: missing midi-block

[pls]

Hey all,

musicxml2ly v2.15.29 currently does not automatically include a(n) 
(out-commented) midi-block in the generated .ly-file when there is 

* only one <part>-element.
* a <part-group> element (with or without a <group-symbol>-element).

The latter is true for the file midi-block-part-group.xml (attached) but not 
necessarily for other files. Some .xml-files containing a <part-group> are 
converted correctly. So there must be something else...

I will submit a patch for the problem mentioned first asap.
