Fix fatal when searching for "r matey prepare to be boarded"
Summary:
See <https://discourse.phabricator-community.org/t/unrecoverable-fatal-error-on-repository-search-in-top-search-bar/503/2>.
The Ferret engine replaced `withNameContains()`, but I missed this obscure callsite.
Test Plan:
- Searched for `r matey prepare to be boarded`.
- Before: fatal.
- After: no fatal.
- Also searched for `r <actual repository name>`, got repository.
