Doesn't work with explicit lifetimes for &self

[asomers]

Attempting to mock a method with an explicit lifetime for the &self argument will result in a panic.

mock!{
    Foo {
        fn foo<'life0>(&'life0 self, x: u32) -> u32;
    }
}

results in

error: proc macro panicked
 --> mockall/tests/mock_life0.rs:5:1
