Conversion Queue status from xml doesn't fail gracefully when Queue status is unavailable.

[troydai]

Occasionally, the Queue service returns unavailable status:

<?xml version="1.0" encoding="utf-8"?><StorageServiceStats><GeoReplication><Status>unavailable</Status><LastSyncTime></LastSyncTime></GeoReplication></StorageServiceStats>

Because of the missing last sync time, deserialization keep throwing TypeError which not only not representing the correct service feedback, but also keeps SDK retrying muliple times.
