The `$module_name` of `com::__construct()` can be a ProgID, ClassID or
moniker. We first try `CLSIDFromString()`, and if that fails, we go
ahead and try to treat the `$module_name` as a moniker. If that also
fails, we throw an exception with the result of `MkParseDisplayName()`
what would just be `MK_E_SYNTAX` if given a ProgID. This result is
highly confusing for the common case where a ProgID is given, which is
not registered (e.g. due to a typo). In this case, we use the original
`HRESULT` (`CO_E_CLASSSTRING`) instead.
