Fix duplicate Review type definition

[gavxue]

Noticed that we accidentally defined the Review type twice for graphql. We just need to remove one.

Before:

• after running docker-compose up

- recruitment_tools_backend  | /app/node_modules/graphql/validation/validate.js:107
recruitment_tools_backend  |     throw new Error(errors.map(function (error) {
recruitment_tools_backend  |           ^
recruitment_tools_backend  | Error: There can be only one type named "Review".
recruitment_tools_backend  | 
recruitment_tools_backend  | Field "Review.passionFSG" can only be defined once.
recruitment_tools_backend  | 
recruitment_tools_backend  | Field "Review.teamPlayer" can only be defined once.
recruitment_tools_backend  | 
recruitment_tools_backend  | Field "Review.desireToLearn" can only be defined once.
recruitment_tools_backend  | 
recruitment_tools_backend  | Field "Review.skill" can only be defined once.
recruitment_tools_backend  | 
recruitment_tools_backend  | Field "Review.skillCategory" can only be defined once.

After:

• running docker-compose up should not cause any errors
