Allow enums that have AbslStringify to be logged as text

Browse Source 
When an enum has AbslStringify, we log the text coming from stringifying it, not the numeric value.


Drive by changes,
1. Changed the tests to use string matchers rather than
   std::string::find.
2. Fixed test includes.
3. Fix spelling.
