inconsistent parsing for time with numbers about duckling

@a86c6f7964 Thanks for reporting!
As you pointed out, the resolution of the first example is wrong.
In the second example, one would expect a single token too.

Maybe related, for the sentence below, I would expect one additional possible result with 8 to 10 years ago as a range of dates. Am I right?

Four of the companies are producing at rates in excess of initial rates of 8 to 10 years ago.

@arademaker Indeed, it should return a single Time entity with span 8 to 10 years ago. Would you be able to look into this and submit a pull request?
