[Explicit Module Builds] Do not attempt to re-load module dependency from

interface for index.

An explicit module build compile is unable to do so because it does not have
access to the interfaces. Doing this in the first place is a workaround for a
known bug, which will require to be solved at the root cause instead (e.g.
Deserialization Safety feature).
