feat(analytics): Bunch of analytics & screen tracking improvements

[jamesdaniels]

• Better handle lazy routes
• Better handle nested routes
• Better handle nested & lazy routes
• Handle multiple outlets correctly
• Handle multiple outlets that share the same lazy components (this was tricky)
• NO LONGER USING INTERNAL APIS OR REQUIRING ANNOTATIONS!!!! 🎉 😄
• APP_NAME and APP_VERSION should be working now...
• AngularFireAnalytics now gets it's measurementId from Analytics rather than your config, there's an edge case where this can change out from underneath you, which the JS SDK handles
• Got DEBUG_MODE working again
