Fix FileNotFoundException on document template

Steps to reproduce:

• Create a document template in Studio named test_document_template
• Create the following automation chain:

  - Context.FetchDocument
  - Context.PushDocument
  - Document.GetParent:
      type: Folder
  - Context.SetVar:
      name: descriptionparent
      value: "@{Document[\"dc:description\"]}"
  - Context.PopDocument
  - Document.SetProperty:
      xpath: "dc:description"
      save: "false"
      value: "@{Context[\"descriptionparent\"]}"
  - Context.SetInputAsVar:
      name: mondocument
  - Render.Document:
      template: "template:test_document_template"
      filename: output.ftl
      mimetype: text/xml
      type: ftl
  - Blob.AttachOnDocument:
      document: "@{Context[\"mondocument\"]}"
      save: "true"
      xpath: "file:content"
  

• Create an event handler linked to the automation chain which:
  • listens to DocumentCreated event
  • is enabled for File document type only
  • is enabled when current document is a mutable document only.
• Hot reload.
• Create a Folder with a description.
• Within the Folder, create a File document.
  => JSF error page appears.

The jar does indeed contain the template (see attachment).
