Include scheduled reports in integration tests #3324

Scheduled reports (PDF, HTML, SMS) are currently not part of the integration test suite.

Questions to address :

• which format should be tested, in particular, PDF might be trickier (see attached example files)
• whether graphs (images) should be included
• which information should be removed, e.g: dates
• which period(s) should be tested
• I have attached a patch for OneVisitorTwoVisitsTest.php, how can it be applied to all integration tests with minimum code duplication ?

I am still experiencing responsiveness issues with Trac & SVN
