export_service macro should honor method name in #[ic_cdk_macros::query(name = "method_name")]

[dansteren]

Describe the bug
If a rust method is exposed to the IC under a different name using the name attribute in #[ic_cdk_macros::query(name = "method_name")], the export_service macro should also honor that name when generating the corresponding candid.

To Reproduce
Steps to reproduce the behavior:

1. Annotate a canister method with #[candid::candid_method(query)] and #[ic_cdk_macros::query(name = "candid_method")]
2. Call the export_service macro
3. Notice that the generated candid exposes the native rust function name, not the name provided to ic_cdk_marcros::query.

OR

1. Clone https://github.com/dansteren/export_service_bug
2. Follow the steps to reproduce listed in the readme

Expected behavior
Calling the export_service macro should generate a candid file where the method matches the name passed to ic_cdk_marcros::query

Ack. We are in the process of merging these two attributes. Before that, candid_method has a rename attribute. If you make it the same as query(name = "..."), it should work.

That worked, Thanks! Just added that rename attribute for now. E.g.

#[candid::candid_method(query, rename = "candid_method")]
#[ic_cdk_macros::query(name = "candid_method")]
pub fn rust_method() -> bool {
    true
}

If it's easy to add into the documenation that would be helpful for others in the future. Otherwise I look forward to the two attributes merging in the future. That will be much better.

Thanks!
