HistoricTradesV2.php incorrect array key when parsing response

[ThatGuyAstro]

Issue

• "mapper" function is trying to resolve response-data via the "ticks" array key, this throws an error. (@ lines 53 and 58)

Solution

• Change the resolving array key to "results"

Not sure what your guys pull-request protocol is... but this is a simple fix so you can prob. just throw into the pipeline of low hanging fruit.

Thanks!

The tests are bad, I am going to work on all the issues this weekend. I am going to push a fix for this in couple of minutes.
