Added code to remove characters that interfere with Surefire report
watching. For SLIM this is no issue because an earlier assertion error
is raised in case of a failure that has no invalid characters and
therefore can be processed by Surefire. 
However for FIT, somehow only these last assertions are raised and the
&lt; and &gt; characters cause the TEST-null.xml not to be processed by
Surefire so any failure logged here was not seen.
