Fix performance for build_operand with dynamic attributes (#106)

# Description ✍️

Improve the `build_operand` performance for dynamic attributes by avoid
an unecessary call for
include? method.

Before when using include? method for a Mongoid::Criteria, it was
triggering an useless
getMore query for Mongo db. Example:

```
[dfd90178-0ec0-4fb5-96bb-976c35a73fa3] MONGODB | mongo:27017 req:1741 | database-prod-db.getMore
