remove fontane analyzer
we don't need the fontane analyzer here, so reset to exist defaults in textgrid/data/collection.xconf
<analyzer id="fontane" class="eu.dariah.de.fontane.lucene.FontaneAnalyzer">
<param name="mappings" type="java.io.FileReader" value="/var/lib/textgrid/charmap.txt"/>
<param name="synonyms" type="java.io.FileReader" value="/var/lib/textgrid/synonyms.txt"/>
</analyzer>
