Content Types ending with "s" can't be saved

[eiskalteschatten]

Describe the bug
When creating a content type that ends in the letter "s", Strapi automatically creates the table in the database using "es" for the plural. The problem is that if you have a component within that content type, the column with the ID added to the component table is correct without the "es", but Strapi looks for it just without the "s".

For example:
Content Type: "about_us"
Table name: "about_uses" (sounds funny, but whatever)
A component is added to the "about_us" content type. In the component table, the "about_us_id" column is added, but Strapi looks for the column "about_use_id".

Steps to reproduce the behavior

1. Create type: "about_us"
2. Create a component and add it to the content type.
3. Start Strapi and create an item of content type "about_us".
4. Try saving. An error is returned.

Expected behavior
The item should be saved and Strapi should look for the column without the "e" that it added to the name.

System

• Node.js version: 10.18.1
• Strapi version: 3.0.0-beta.18.6
• Database: Postgres
• Operating system: Linux
