docs: Returns the path to be searched by first looking for an entry in the manifest of the bundle specified by
  path manifest header. It will return the default path if:
  - path manifest header is null
  - header is not set
  - header is not a string
  - header is empty
  
  @param bundle bundle containing the manifest
  
  @return found path
