Overwrite whereIn function in MorphMany relation.

[skuio]

When we using MorphMany relation, this Exception occurred:
Call to undefined method Jenssegers\Mongodb\Query\Builder::compileWhereInRaw()

This PR overwrite whereInMethod function to return whereIn instade of the default (whereInRaw).

We try to solve the check errors, but still, we have some errors we can't solve it.

• The "WordPress.WP.PreparedSQL" sniff has been renamed to "WordPress.DB.PreparedSQL". Please update your custom ruleset.

• The "WordPress.XSS.EscapeOutput" sniff has been renamed to "WordPress.Security.EscapeOutput". Please update your custom ruleset.

• Avoid unused parameters such as '$key'. we overwrite function only!

protected function whereInMethod(EloquentModel $model, $key) { return 'whereIn'; }

How to solve these errors?

Thanks!

Warnings about WordPress linked with settings for Codacy. I think that him changing are available only @jenssegers. Avoid unused parameters such as '$key' absolutely correct because args in function don't use. Original function
