Retry Flickr search without middle initial when no results found

When the default phrase search returns no results and the name contains
a middle initial (e.g. "Gary B. Fogel"), automatically retry with the
middle initial removed ("Gary Fogel"). Only applies to the default
search, not user-overridden searches.
