fix(upload): prevent crash and duplicate retries when retrying failed uploads

[alperozturk96]

Changes

• Catch AccountUtils.AccountNotFoundException around createOwnCloudClient
• Run retries on an injected application-scoped CoroutineScope
• Replace the launch-only Semaphore with an AtomicBoolean
• Provide @ApplicationScope CoroutineScope via DispatcherModule
• Use by lazy for the singleton and drop the broken isUploadStarted return value since events are used in worker.
• Implements createOwncloudClient for UserAccountManager and add tests
