Description

1) Special thanks go to Angel Luis Jimenez Martinez for both finding the problem, and finding the one line of code that caused this problem.

This only affects the TokenNameFinder when parsing user input and tagging the output.
The problem was when the name finder model returns the spans, it would properly find the Spans and return them; however, it would improperly label the Spans when constructing them, if they where back-to-back.
This can cause the NameFinder to improperly report the wrong tag in this situation.
