There's no reason for `_waitForDownload` to be responsible for
constructing a new Realm instance when we can instead use the
constructor for that. This eliminates the potential for different
handling of the Realm configuration between `_waitForDownload` and `new
Realm`, which was responsible for various issues (#1391, #1392, #1393).
In turn, this requires that `_waitForDownload` become an instance method.
In addition, we update `Realm.openAsync` and `getSpecialPurposeRealm` to
delegate to `Realm.open` rather than reimplementing equivalent logic
themselves.
Finally, the private mechanism for registering a download progress
handler as part of the sync configuration (`_onDownloadProgress`) is
removed in favor of the public API (`progress()` on the promise returned
by `Realm.open`).
