The existing handling for data source state transitions when receiving `sse` errors was incorrect. It was treating any error as a state transition to `kOff/kShutdown`, and logging at the `error` level. The correct behavior would be making that transition only if the error is unrecoverable. Additionally, recoverable errors should be logged at the debug level, in order to not overstate the impact of the issue. This bug did not actually affect the backoff behavior of the eventsource, but it did impact status listeners and any code that queried the existing status within the SDK.

The existing handling for data source state transitions when receiving
sseerrors was incorrect. It was treating any error as a state transition tokOff/kShutdown, and logging at theerrorlevel.The correct behavior would be making that transition only if the error is unrecoverable. Additionally, recoverable errors should be logged at the debug level, in order to not overstate the impact of the issue.
This bug did not actually affect the backoff behavior of the eventsource, but it did impact any status listeners which was certainly misleading.
