`#[validate(...)]` helper attribute does not coexist with other helper attribute

[naskya]

#[validate(...)] helper attribute does not coexist with other ident-only (#[foo]) helper attribute. The Test4 struct in the following code produces an compilation error.

// compiles
#[derive(Validate, Foo)]
struct Test1 {
    #[validate(nested)]
    a: A,
}

// compiles
#[derive(Validate, Foo)]
struct Test2 {
    #[validate(nested)]
    #[foo(foo)]
    a: A,
}

// compiles
#[derive(Validate, Foo)]
struct Test3 {
    #[validate(nested)]
    #[foo = "foo"]
    a: A,
}

// this does not compile
#[derive(Validate, Foo)]
struct Test4 {
    #[validate(nested)]
    #[foo]
    a: A,
}

#[derive(Validate)]
struct A {}

 error: You need to set at least one validator on field `a`

         = note: If you want nested validation, use `#[validate(nested)]`

Anyway, thank you for maintaining this awesome project!

Looks like we might not be validating the name of the attribute?
