Issues with identical contract names

I am seeing weird behavior when having contracts with identical names, but placed in different separate subfolders

In one project, I noticed that the barrel export index.ts only included one of the contracts and not the other. I wasn't notified of this and this was misleading on places where i expected the other contract.
```json
"@typechain/ethers-v5": "^10.2.0",
"@typechain/hardhat": "^6.1.5",
"ethers": "^5.7.2",
"hardhat": "^2.14.0",
"typechain": "^8.1.1",
"typescript": "^5.0.4"
```

On a fresh hardhat project, typechain was failing, new extra folders with the names of the subfolders were created in the root folder, with `Contract__factory.ts` in each.
