Fix a bug when creating FlowId and FlowBatchId from hex string:

 * Added static methods FlowId.valueOf(String) and FlowBatchId.valueOf(String)
   Implementation-wise, those methods are practically same as
   IntentId.valueOf(String)

 * Used the above methods as appropriate.

This fixes an exception that for some reason only occasionally shows-up
in logs of some of the unit tests, and also does not break those tests.

Also, make the change to accept hex strings starting with either 0x or 0X.
