Migrate instances of lodash.assign to object.assign

[carbonrobot]

Replace instances of lodash.assign with Object.assign.

Functionally, in all our use cases these two methods are equivalent. The exception is that lodash.assign allows undefined as a first argument. The only case we had where this is an issue was events.ts where we simply check for undefined as a workaround. All other usages pass a new object as a first argument.

Also replaces usages of lodash.merge in the demo. We didn't use any specific to merge so its safe to use assign instead.
