Jeremy Felt d759c0ef23 Check for existence of data from get_blogaddress_by_id() before returning a URL
* Prevent a notice when an invalid ID is used with `get_blogaddres_by_id()`.
* Return a falsy empty string rather than the previous "http://".
* Add unit tests for `get_blogaddress_by_id()`.

Props nerrad.
