Describe the bug

I'm trying to use the sol! macro to get signature hashes for events, but it seems having the same name for 2 different events messes with the hashes of both:

sol! {
    event TestEvent(bytes32 indexed one);
    event TestEvent(bytes32 indexed one, bytes32 indexed two);
}

main() {
    println!("test1: {:?}", TestEvent_0::SIGNATURE_HASH);
    println!("test2: {:?}", TestEvent_0::SIGNATURE_HASH);
}

this leads to
0x4126a29fd17029d376521f62e26c90187da40445c02353770fc7f104fdcf4aad
and
0x5605e19697b8c6a8f1030e73a4c1ee8f95910ba367148f89949f77cb79d3d5ce

whereas removing the second TestEvent and taking the first's signature yields the correct one: 0x2d87364d1542bf89b684ede9ddff45aed45971c6f05deaca687bd3d1b6caf1c3
