Count not working with embedded models

[prtkkmrsngh]

All api are returning count as 0 where relations type is embedsMany.

For example
In repository loopback-example-relations
following api returns count 0 after adding any number of emails.
http://localhost:3000/api/Customers/1/emails/count

There is a bug logged for relations embedsMany count not working.

Closing this as a dup.
