Link to issue number:

None

Summary of the issue:

shouldUseToUnicodeEx can sometimes result in none object has no property helperLocalBindingHandle error. This is hard to reproduce but I've seen it often in WhatsApp UWP.

Description of user facing changes

None known.

Description of development approach

1. When checking for helperLocalBindingHandle, ensure that appModule has a value.
2. While at it, reorder the checks, since in current era, UWP applications are much more common than during the initial implementation of this approach.

Testing strategy:

Should be tested during daily use as it is hard to reproduce the underlying issue.
