XmlUtil.xmlCollapseWhitespace() throws StringIndexOutOfBoundsException on empty attribute

Hi @pdvrieze, I faced a small bug in the latest version (0.86.2; 0.86.1 is not affected). The following line ends up with a StringIndexOutOfBoundsException if original: String is empty:

xmlutil/core/src/commonMain/kotlin/nl/adaptivity/xmlutil/XmlUtil.kt

Line 49 in d375df5

if (last == ' ') this.deleteAt(this.length - 1) // make sure to trim

Just fixed it. Thanks for the report. This is indeed new code, taken from my work on xml schema support (that requires support for collapsing whitespace). In terms of serialization it is used for/needed for supporting attribute lists and attribute maps.

Thanks a lot for the quick fix!
