Bug fix for #757 - write all name table entries for fonts crafted from scratch (#758)

* Main bug fix

 - `for...in` loop iterates over keys in `names` object, not indexes of an array of strings
 - if `uniqueID` or `postScriptName` is found to be missing, update the platform that is currently being looped over, not just the `unicode` platform.

* Added tests for new name table entries

Test now checks for defaults for `postScriptName` and also `uniqueID`

Generating a `uniqueID` now provides a fallback empty string if no `manufacturer` exists.
