Naz 143921948d Fixed "no-shadow" eslint warning in tests
refs b6728ecb0f

- The "no-shadow" eslint rune was introduced into ghost's eslint plugin (referenced commmit), which resulted in flood of warning in console output when linting the project codebase.
- This cleanup is aiming to make any new linting issues more visible. Follow up commits will contain similar cleanups in other parts of the codebase
