Summary0001805: When switching from XM to IT/MPTM, the volume loop of the instrument gets incorrect values.
Description

I tried to save an XM module in IT format, but the saved IT module is played incorrectly by OpenMPT and all players.
When switching to IT or MPTM, the volume envelope loop and sustain loop of the instrument gets incorrect values.

Steps To Reproduce

0.: Download this song: https://modarchive.org/index.php?request=view_by_moduleid&query=185350
1.: Open it and start playback.
2.: Stop it and change the Type to IT or OpenMPT in the "Song Properties" window.
3.: Start playback again.
4.: The beginning of the song will sound wrong due to the problem mentioned above.

As of r21301, if an XM volume envelope has sustain point or loop, sustain is now automatically enabled on the last point for IT/MPTM conversions.

It looks like it's only partially okay.
With the same module, if I switch to IT/MPTM, Instrument 47 sounds wrong.
