Fix Auth0 publisher bug with connection vs connectionStrategy
Fix Auth0 publisher bug with connection vs connectionStrategy

#335 seeks to fix this bug but didn't catch the actual root cause. The activate-new-users-in-CIS rule was comparing both `context.connectionStrategy` and `identity.connection` which comes from `context.connection` to the `WHITELISTED_CONNECTIONS` value.

The problem with this is that `connection` and `connectionStrategy` have different values.

* connectionStrategy is github and identity.connection is github
* connectionStrategy is email and identity.connection is email
* connectionStrategy is google-oauth2 and identity.connection is google-oauth2
* connectionStrategy is ad and identity.connection is Mozilla-LDAP-Dev
* connectionStrategy is oauth2 and identity.connection is firefoxaccounts

Specifically LDAP and FxA have different values.

This corrects this by reverting #335 and changing to only use `connection` not `connectionStrategy`
