"struct:error:name" and "struct:field:name" not work together

[mrsndmn]

Following code

var Result = ResultType("application/vnd.goa.error", func() {
    Attribute("error", String, func() {
        Meta("struct:error:name")
        Meta("struct:field:name", "ErrorCode")
    })
    Required("error")
})

Generated code:

type GoaError struct {
    ErrorCode string
}

// Error returns an error description.
func (e *GoaError) Error() string {
    return ""
}

// ErrorName returns "GoaError".
func (e *GoaError) ErrorName() string {
    return e.Error
}

This code won't be compiled:

cannot use e.Error (type func() string) as type string in return argument

Good catch! thank you. Can you please back-port to the v2 branch as well? (simply cherry-pick the merge commit).
