We were already using `find_by` most of the time.
Since there are false positives related to our `find_by_slug_or_id!` and
`find_by_manger_login` methods, which cannot be replaced with `find_by`,
I'm adding it indicating the "refactor" severity.
After creating a translation in spanish, it was also displaying it when selecting
the english locale.
This was due to the code picking the first translation available
With this commit, we are checking for an existing translation in the current locale
and displaying it if it exists
