* When refreshing the token, look up the user in a way that doesn't suffer
from #1586
Expose a means of looking up a user by identity and server to avoid
problems if the same user identity exists for multiple servers, which
can happen when connecting to the same server via different hostnames.
* Return undefined if the user doesn't exist rather than returning an object wrapping a null SyncUser.
* Adding method Realm.Sync.User.authenticate()
* Adding JWT provider support to Realm.Sync.User.authenticate()
* Adding password provider support to Realm.Sync.User.authenticate()
being open with a different schema version
In order to correctly open read-only synchronized Realms, `Realm.open`
would open the Realm without specifying a schema or schema version, wait
for any remote changes to be downloaded (if appropriate), and then
re-open the Realm with the specified schema and schema version. This
would lead to an exception about the Realm being open with a different
schema version if the Realm had previously been opened with a different
schema version, due to the way `RealmCoordinator` caches information
about the schema of open Realms.
We address this by making two changes:
1. `Realm.open` for non-synchronized Realms no longer goes through
`_waitForDownload`. This means the dance described above where the Realm
is opened twice is not used for local Realms.
2. `_waitForDownload` no longer keeps the `Realm` alive until after its
callback has returned. It instead keeps the `SyncSession` alive. This is
sufficient to avoid the connection being torn down and having to
reconnect when `_waitForDownload`'s callback later opens the Realm with
the correct schema and schema version, while also allowing for
`RealmCoordinator`'s cached information to be cleared when the
schemaless Realm is closed prior to the Realm being reopened.
In addition, tests have been added that reproduced the problem in both a
local and sync context.
