Handle type annotations on method reference qualifiers

e.g.

```
Supplier<List<?>> a = @A(0x45) ArrayList::new;
Supplier<List<?>> b = @A(0x46) ImmutableList::of;
```

The necessary logic is already there, but the start position information
for the method reference doesn't include the leading type annotations,
which was resulting in an assertion to fail.
