fix(conversation): fixing bookmarks without resource.name

[whitdog47]

This pull request addresses an issue in the add_conversation_bookmark function where bookmarks could not be added if the resource object lacked a name attribute. The changes ensure that a bookmark can still be created by using alternative identifiers when resource.name is unavailable.

Changes Made

• Refactored Resource Name Handling:
  • Introduced a new logic to determine resource_name when resource.name is not present. It now checks for resource.resource_type and uses deslug_and_capitalize_resource_type to generate a name. If neither is available, it defaults to the provided title or "untitled resource".
• Updated Log Messages:
  • Modified log messages to use resource_name instead of directly accessing resource.name, ensuring consistent and meaningful logging even when resource.name is absent.
• Code Adjustments:
  • Adjusted the conditional checks and log messages throughout the function to accommodate the new resource_name logic.
