Changes

scripting: Update the XY views to new tracecompass API

Trace Compass has moved from org.swtchart to org.eclipse.swtchart and
updated its API accordingly. The scripting views had not been updated
for it and the styles of scatter and histogram charts did not work
anymore (they were all line chart).

opentracing: Add span to root if parent not found

If the quark for a parent span ID does not exist, add the span at the
child span at the root of the trace's span instead of returning.
