[google-analytics] useGoogleAmpClientId should be useAmpClientId

[SegmentDestinationsBot]

Migrated from #79 by @westcoastbias

currently the ga creation with useGoogleAmpClientId set to true looks like this:

Running command: ga("create", "UA-81924801-3", {cookieDomain: "none", siteSpeedSampleRate: 1, sampleRate: 100, allowLinker: true, useGoogleAmpClientId: true})

GA debugger chrome tool throws the following warning:

Create config had an unknown parameter: "useGoogleAmpClientId"

Based on google's documentation on implementing AMP (https://support.google.com/analytics/answer/7486764), the field should be "useAmpClientId". Example from the docs:

ga('create', 'UA-XXXXX-Y', 'auto', {'useAmpClientId': true});

This results in different client ids being used for AMP vs non-AMP events, which results in two separate sessions.
