- set leak period to 30 days
- analyze a project using date more than 30 days ago (-Dsonar.projectDate)
- analyze a project using date 15 days ago
- you'd expect to see "last analysis 15 days ago", but instead you see the period since first analysis
When the leak period has a moving start date (a 30 days period for example) we should not show the last analysis date. Because the goal of this date is to know the size of the leak period, but when the period is defined like that, the user already know its duration, there is no need to show a date that could be outside of the range.
