JavaScript automation chains list not correctly updated on hot-reload

Creating a new JS chain and calling it in an existing one is not recognized. You have to restart the server.

• Say you have a JS Automation chain, for example MyJS
• Create a new one. For example, DoThis
• In MyJS, call DoThis:

  • • •
  result = DoThis(input; {});
  • • •
  

• Deploy the changes via Hot Reload ("Update" in the Admin Center)
• Test the changes => This leads to an error:

  . . .
  [...] Could not run the chain: javascript.MyJS
  org.nuxeo.ecm.automation.TraceException: 
  
  ****** chain ******
  Name: javascript.MyJS
  Exception: OperationException
  Caught error: Failed to invoke operation javascript.MyJS
  Caused by: <eval>:25 TypeError: Cannot call undefined
  . . .
  

The line #25 is the line calling javascript.DoThis.

To make the thing work, you have to restart the server.
