GA ecommerce/multipe events bug(s)

#### Bug 1

When I add an integer or float to a hash being send to GA, the value should be send as a string in the javascript (see: https://developers.google.com/analytics/devguides/collection/analyticsjs/ecommerce#addTrans)

#### Bug 2

I'm trying to send an `addTransaction` an `addItem` and an generic `event` to GA, but the last event is somehow getting dropped :(
