fix(db-mongodb): duplicate ids in sanitizeQueryValue

[kholiavko-roman]

What?

Fixes duplicated ids in MongoDB requests.

In case a collection has a relationship one to many with another collection

 {
    name: 'topics',
    label: 'Topics',
    type: 'relationship',
    relationTo: 'topics',
    hasMany: true,
  },

And we are trying to render the nested collection, in this case, topics, mongo db adapter insert duplicated ids in the requests

Why?

To remove duplicated id's in requests.

How?

Added return to sanitizeQueryValue where formattedValue is built. It seems like that the reduce function should add only 1 item to formattedValues for 1 iteration.

The problem is still actual and annoying, any change that you guys can take a look?
