Only last contract declaration appears in compilation output

[joss-aztec]

Aim

To have access to build products for all contracts within a project.

Expected behavior

The compilation output should contain build products for all contracts defined within the project.

Bug

When compiling the following:

contract Foo {
    fn do_foo(input: pub Field) -> pub Field {
        input + 1
    }
}

contract Bar {
    fn do_bar(input: pub Field) -> pub Field {
        input + 2
    }
}

contract Baz {
    fn do_baz(input: pub Field) -> pub Field {
        input + 3
    }
}

The json compilation output only contains products for the last contract (Baz).

{
  "name": "Baz",
  "backend": "acvm-backend-barretenberg",
  "functions": [
    {
      "name": "do_baz",
      "function_type": "Secret",
      "abi": {
        "parameters": [
          {
            "name": "input",
            "type": { "kind": "field" },
            "visibility": "public"
          }
        ],
        "param_witnesses": { "input": [1] },
        "return_type": { "kind": "field" },
        "return_witnesses": [2]
      },
      "bytecode": [/* CUT */],
      "proving_key": [/* CUT */],
      "verification_key": [/* CUT */]
    }
  ]
}
