Unhandled error when storing access token in OAuthImpl

[ivanrein]

Our users have been reporting issues where they keep getting signed out of Dropbox after quitting the app and relaunching.
This is how we're doing our setup and auth:

1. on app launch, DropboxClientsManager.setupWithAppKey(.apiKey) is called
2. sign in using DropboxClientsManager.authorizeFromControllerV2
3. call DropboxClientsManager.handleRedirectURL
4. now DropboxClientsManager.authorizedClient is not nil.
5. on next app launch, we call DropboxClientsManager.setupWithAppKey(.apiKey) again, but DropboxClientsManager.authorizedClient is still nil for some users.

after further digging into handleRedirectURL call, I found this line where result of storeAccessToken is ignored. In the case of storeAccessToken returns false, the access token is not persisted for next app launch.
This could mean that for those problematic users, after calling DropboxClientsManager.setupWithAppKey(.apiKey), it may fail to setup authorizedClient in this line.
I can't verify this though or inform users why it fails since there's no logging visible from my app. Could someone help?
