Subject: [PATCH] bpo-37025: Fix implementation of capturing our activation context

This commit contains three fixes:

1. Fix AddRefActCtx() not returning a value
2. Calling AddRefActCtx() only make sense with a valid and not zero
   context returned by GetCurrentActCtx()
3. Fix printing an error message in case the current activation context
   could not be loaded
