Fix Lint/DuplicateRequire issue

[cyrillefr]

What? Why?

• Contributes to Fix Rubocop Rails issues #11482

Fixes one of many rubocop issues:

• cop class: RuboCop::Cop::Lint::DuplicateRequire
• that is: some requires are made twice
• .rubocop_todo.yml updated

What should we test?

Nothing: this is all about syntax linting and how rubocop should raise no offenses on the above cop when checking.
