null uriToProblem in validation issue

[RimShao]

Hi,

In certain syntax issue 'uriToProblem' is null, right now we need additionally to fill the 'URI' value into Issues, otherwise can't resolve file the syntax errors report to. it would be great that yang-lsp can fix that.

use below test model can reproduce the problem, the syntax error is because of unbalanced brace in 'when' statement.

leaf key-id {
        type string;

        when "/ctxsr6k:contexts/ctxr6k:context/ctxr6k:context-"
             + "name='local'" {
                  description
                  "";
         }
         }
}

@RimShao Would resource URI as uriToProblem work for you?
