Rebuild not triggered when  deletion with nested modules

It seems in some cases when working with nested modules there can be some correctness issue with the build. Here's a minimal repro I've found:

```rescript
// Test_A.res
let foo = 1
```

```rescript
// Test_B.res
module A = Test_A
```

```rescript
// Test_C.res
let bar = Test_B.A.foo
```

Expecting a compile error after deleting `Test_B.res`.
