[musicxml export] - Strange duplication and missing object

[hhpmusic]

Issue type

Import/export issue

Description with steps to reproduce

When I convert this:
http://musescore.com/user/1397281/scores/27889063
I found at m60-61, there are two issues. I'm not sure if they are from the same problem. I'm using the artifact build with issue #27265 is solved.

1. m60, there are two diminuendo hairpins at the same place, one short and one long. The beginning of the long one is missing.
2. At m61, "p picchietando" is duplicated, thus there are two pieces of dynamic and text.
