Identically named structs cause failure when parsing seeds for the IDL

[RuvendeGroote]

Hi,

related to, but not identical to, issue #2441, running anchor build on following program

use anchor_lang::prelude::*;

declare_id!("Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS");

#[program]
pub mod bug {
    use super::*;

    pub fn initialize(ctx: Context<Initialize>) -> Result<()> {
        ctx.accounts.something.first = 0;
        Ok(())
    }
}

#[derive(Accounts)]
pub struct Initialize<'info> {
    #[account(
        seeds = [&something.first.to_le_bytes()],
        bump
    )]
    pub something: Account<'info, Something>,
}

#[account]
pub struct Something {
    pub first: u64,
}

mod other {
    use anchor_lang::prelude::*;

    #[derive(AnchorDeserialize, AnchorSerialize)]
    pub struct Something {
        pub second: u64,
    }
}

results in

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', lang/syn/src/idl/pda.rs:336:22`

Tested with 0.26.0 and 0.27.0.

you have to turn on the seeds feature first of course

Fixed in #2824.
