"Validation errors" layer should be added below data layers

[mkoniecz]

When I create "Validation errors" layer by validating some OSM data, it is put at the top of the stack.

Once I use "Zoom to problem" the line is obscured by marking line with very wide line - see attachment default.png

Switching layers makes possible to again see marked way - see attachment better.png

Maybe it would be better fixing by changing complete fill into something more discreet (half transparent fill)?
