[BUG] One more generics issue (`fn name<P: Type<Type>>(){}`)

[eirnym]

Describe the bug
Plugin does nothing if generics contain specialization

Original Code (with line to generate on)

pub fn do_nada<P: AsRef<std::path::Path>>(path: P) {}

while following code works just fine

pub fn do_nada_where<P>(path: P)
where
    P: AsRef<std::path::Path>,
{
}
