`init` macro does not work

[Christian Müller]

I have a function annotated as follows:

#[ic_cdk_macros::init]
fn init() {
    unsafe {
        SOME_MAP = Some(HashMap::new());
    }
}

This code compiles and can be deployed to the local replica, however the global variable stays uninitialized. When I change ic_cdk_macros::init to ic_cdk_macros::update and call init explicitly, everything works as expected and the variable is initialized. Hence I conclude that the init macro has no effect for some reason.
