If the same resource name is in a root and sub dir then with local or

all it should not hit the root one.

everything is the same as lessc compiler is outputitng except the
"off.css" which url15 works like the others that we do resolve it even
if it shouldn't according to lessc
Because url14 'test.jpg' is already mapping on the root image so
so url15 '../test.jpg' shouldn't be there (its above root). But we fall
back to always map it on the root anyway,
