xml: Remove work-around that formats trace path on Windows

This workaround was implemented due to a issue on Windows when using
the XmlConfigurationSource with the Trace Compass trace server and
with theia-trace-extension. Now the Theia platform always provides a
path in the format of the user's platform, the work-around is no longer
needed.
