False positive missing_const_for_fn if there are #[start] and #[test] both are present

[alex-semenyuk]

Summary

False positive missing_const_for_fn if there are #[start] and #[test] both are present since the check is_entrypoint_fn doesn't filter for triggering on entrypoint in this case

rust-clippy/clippy_lints/src/missing_const_for_fn.rs

Line 104 in ad69c65

if in_external_macro(cx.tcx.sess, span) || is_entrypoint_fn(cx, def_id.to_def_id()) {

Reproducer

I tried this code:
https://github.com/rust-lang/rust-clippy/pull/13945/files#diff-2848b9a3191892d7b27e3403ff872cfc21bdcace40abf2f47a90dfd210449f23

I expected to see this happen:
No trigger missing_const_for_fn for entrypoint

Instead, this happened:
Triggered missing_const_for_fn for entrypoint
