17011	Multiple warnings for same problem	GerdP	team	"==== What steps will reproduce the problem?
1. Create two closed ways tagged natural=water which overlap
2. Run validator

==== What is the expected result?
One warning showing the two ways
==== What happens instead?
5 Warnings and 2 informations
{{{
Warnings (5)
- Crossing ways (1)
- Overlapping Identical Natural Areas (2)
- Overlapping Water Areas (2)
Other (2)
- Overlapping Areas (2)
}}}
==== Please provide any additional information below. Attach a screenshot if possible.
The first warning is produced by validation.tests.CrossingWays, the others by MapCSSTagChecker. We should reduce the noise. I think the test in CrossingWays is better because it shows better where the overlap is.
