Report to filter by project to include subprojects

[danihodovic]

If I divide my Taskwarrior tasks into subprojects, e.g

task add Write code project:taskwarrior.backend
task add Write styles project:taskwarrior.web

and I decide to filter the timewarrior report by the parent project

timew summary :month taskwarrior

Timewarrior will only return tasks that belong to the root project timewarrior. I would expect it to return a report for all sub projects of timewarrior
