Bug: Re-encode monolith wipes sample map

[d.healey]

Steps to reproduce:

• Map some samples.
• Save the sample map
• In an empty sampler select tools >> reencode monolith from the context menu
• Use the file browser to select the sample map
• Click Ok

A popup will instantly appear and say all samples were successfully converted - but it's all lies!!! What will actually happen is you will get a corrupt monolith file and a sample map looking something like this:

<?xml version="1.0" encoding="UTF-8"?>

<samplemap ID="staccato" SaveMode="2" RRGroupAmount="1" MicPositions=";"/>

I did this test using a sample map with 3 mic positions
