`#[actor]` macro does not support generic structs

[LeonMatthesKDAB]

Expected Behavior

Adding #[actor] onto a generic struct should work or otherwise provide a descriptive error message.

e.g.:

#[actor]
struct MyActor<A> {
    client: A
}

Actual Behavior

The compiler generates a (somewhat confusing) error message:

error[E0107]: missing generics for struct `MyActor`
  --> src/actor/mod.rs:62:8
   |
62 | struct MyActor<A> {
   |        ^^^^^^^ expected 1 generic argument
   |
note: struct defined here, with 1 generic parameter: `A`
  --> src/actor/mod.rs:62:8
   |
62 | struct MyActor<A> {
   |        ^^^^^^^ -
help: add missing generic argument
   |
62 | struct MyActor<A><A> {
   |               +++

Steps to Reproduce the Problem

On version 0.16, use the #[actor] macro on a generic struct:

#[actor]
struct MyActor<A> {
    client: A
}

Then try to compile the code.
