Add braces to the fast-path if statement.

Change line 26 to use a block. This keeps the optimization unchanged and complies with the rule: “Always use curly braces for if, else, loops, and similar control statements.”

Proposed fix 
-  if (path.indexOf('//') === -1) return path
+  if (path.indexOf('//') === -1) {
+    return path
+  }

As per coding guidelines, TypeScript control statements must always use curly braces.
