MoEngage Destination | Anon ID is overwriting User ID

Hello, everyone!

My name is Marcos Landi, I'm using RudderStack at CloudWalk and found an issue connecting to MoEngage. When we have anonymousId and userId at the same event, the anonymousId overwrite the userId.

Following other destinations' behavior, analytics value and the fact that an Anon ID is temporary and a User ID permanent, it is better for us (and possibly all other RudderStack users) to prioritize the User ID over Anon ID.

If you guys need a quick call or evidence from our account, please let me know!
