merging `wit` is not commutative

[karthik2804]

As the title states merging wit fails when trying to merge a non minimized package into a minimized package but the other way works. An example is the wit extracted from a component after it has passed through wit-component.

An example would wit-1

package wasi:io@0.2.0 {
  interface error {
    resource error;
  }
  interface streams {
    use error.{error};

    resource output-stream {
      check-write: func() -> result<u64, stream-error>;
      write: func(contents: list<u8>) -> result<_, stream-error>;
      blocking-write-and-flush: func(contents: list<u8>) -> result<_, stream-error>;
      blocking-flush: func() -> result<_, stream-error>;
    }

    variant stream-error {
      last-operation-failed(error),
      closed,
    }

    resource input-stream;
  }
}

wit-2

package wasi:io@0.2.0 {
  interface error {
    resource error {
      to-debug-string: func() -> string;
    }
  }
  interface poll {
    resource pollable {
      ready: func() -> bool;
      block: func();
    }

    poll: func(in: list<borrow<pollable>>) -> list<u32>;
  }
  interface streams {
    use error.{error};
    use poll.{pollable};

    variant stream-error {
      last-operation-failed(error),
      closed,
    }

    resource input-stream {
      read: func(len: u64) -> result<list<u8>, stream-error>;
      blocking-read: func(len: u64) -> result<list<u8>, stream-error>;
      skip: func(len: u64) -> result<u64, stream-error>;
      blocking-skip: func(len: u64) -> result<u64, stream-error>;
      subscribe: func() -> pollable;
    }

    resource output-stream {
      check-write: func() -> result<u64, stream-error>;
      write: func(contents: list<u8>) -> result<_, stream-error>;
      blocking-write-and-flush: func(contents: list<u8>) -> result<_, stream-error>;
      flush: func() -> result<_, stream-error>;
      blocking-flush: func() -> result<_, stream-error>;
      subscribe: func() -> pollable;
      write-zeroes: func(len: u64) -> result<_, stream-error>;
      blocking-write-zeroes-and-flush: func(len: u64) -> result<_, stream-error>;
      splice: func(src: borrow<input-stream>, len: u64) -> result<u64, stream-error>;
      blocking-splice: func(src: borrow<input-stream>, len: u64) -> result<u64, stream-error>;
    }
  }
  world imports {
    import error;
    import poll;
    import streams;
  }
}

Merging wit-1 into wit-2 works but not the other way around
