Fix last test failing on CI

Tests response from javadoc. Failing on java 11 expecting
"https://docs.oracle.com/javase" for both java 8 and 11. On 11 have
the following response:

Clearly fine just bad prefix

```
{:javadoc
  "https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java.base/java/lang/StringBuilder.html#capacity()",
  :throws [],
  :file [],
  :arglists-str "[this]",
  :argtypes [],
  :member "capacity",
  :modifiers "#{:public :bridge :synthetic}",
  :status #{"done"},
  :id "5174fd6d-4f65-4524-babb-07bc2ef2dcb3",
  :class "java.lang.StringBuilder",
  :returns "int",
  :session #{"b85884cb-3503-428c-8123-5c970dd08605"}}
```
