Interface with an overlapping name used internally will cause build error

[jsturtevant]

If you have a wit file with:

package wasi-sample:example;

world example {
  import host;
  export adder;
}

interface adder {
  add: func(left: u32, right: u32) -> u32;
  call-host-function: func(input: string);
}

interface host {
  host-function: func(input: string) -> string;
}

you will end up with errors

looks like this might be caused because the relative call here:
