transaction.name no longer has multi-field mapping

I ran apm-integration-testing today and noticed that basically everything is failing. Tracked it down to the "transaction.name.keyword" match which is failing because there is no such field. It's just transaction.name with keyword type.

IIUC, the index template should define that mapping, but it's not:

Yep, on master "apm-server export template" doesn't include any of our fields. Bisected to a64eb29.

awesome catch @axw! Hopefully this is also going to fix elastic/apm-integration-testing/issues/73
