Bug Description

When we set relations between two models and child naming case is uppercase, then the eager loading doesn't create the proper name for the property since 7.0.0-alpha.36.
I tested in 7.0.0-alpha.35 and this issue wasn't there so it has been introduced since 7.0.0-alpha.36.
That's database agnostic.

Reproducible Example

Let say we have a parent model FOO and a child model BAR.
Then we configure relationship with hasMany and belongsTo

Here is the link to the SSCCE for this issue: here

What do you expect to happen?

If we fetch the parent model with eager loading, we should see child instances under the BARs property

Example: (child model is ACV) :

What is actually happening?

If we fetch the parent model with eager loading, we can see child instances under the bARs property

Example: (child model is ACV) :

In our conventions, we consider attributes and associations to be class properties, and therefore recommend naming them in lowerCamelCase. We also generate the default names in lowerCamelCase.

You can customize your association name using the as option. If you use the class-based definition, it will automatically use the name of the property: https://sequelize.org/docs/v7/associations/has-one/#defining-the-association
