Sonar Unit Test reporter is not working well with suitepath

If a test run contains suitepath, the sonar test execution XML contains something like:
```xml
<testExecutions version="1">
  <file path="equity_pm_database_all">
    <file path="ODS/INSTALL/UNIT_TEST/EQ_PM/PACKAGES/UT_ANALYST_ASSIGN_COV.pkb">
      <testCase name="ut_prc_get_assign_cov" duration="311" >
      </testCase>
    </file>
```
This is not a valid XML
