[Bug][Compiler-v2] No check on duplicated acquires

[rahxephon89]

🐛 Bug

For the following code

module 0x8675309::A {
    use std::signer;
    struct T1 has key {v: u64}

    public fun test(account: &signer) acquires T1, T1 {
        borrow_global_mut<T1>(signer::address_of(account));
    }
}

V1 will generate the following error:

error[E02001]: duplicate declaration, item, or annotation
  ┌─ tests/move_check/translated_ir_tests/move/borrow_tests/borrow_global_acquires_duplicate_annotation.move:5:52

  │                                                Item previously listed here

But V2 does not generate any errors.
