Instead of having two methods here why not just

GURL GetBaseURLAndQuery(const GURL& url, std::string* query)

where query can be NULL.

Mainly because I didn't want to have some nullptr in most call sites, as this
method is used a lot more than the other. WDYT?

+// Extract the query string from an URL and returns the base URL (without the
+// query string), and the query string. If the url doesn't have a query string,
+// it returns the url itself and an empty string.
