Subject: [PATCH] [FIX] report_xlsx: correctly handle exceptions, when
 generating report

Before this commit, when exception is raised while generating report,
on browser window instead of python traceback nothing was shown
on production environment or werkzeug's "Console locked" message
on development environment.
