IMessageSession is not accessible for Recoverability/Startup

[lailabougria]

The IMessageSession is not accessible in Startup or Recoverability scenarios.

All send-operations need to occur as part of the message processing pipeline or an Azure Trigger that can make use of the IFunctionEndpoint object.

Scenario:
Let's consider a scenario in which we want to hook into the OnMessageSentToErrorQueue method to Publish a message right before a message is moved to the error queue. In that case, we don't have access to the IMessageSession.
