Update UI when deleting last point of shape with Path tool (#979)

* Added new DocumentResponse variant

* Update Operation::DeleteSelectedManipulatorPoints to update Layer Tree by delegating deletion to Operation::DeleteLayer. Also emits Operation::DeletedSelectedManipulatorPoints to let editor clear Properties panel

* Update process_message() to deal with new DocumentResponse::DeletedSelectedManipulatorPoints match case. When this DocumentResponse is emitted, it clears the Properties panel.

* Added Display trait implementation for DocumentResponse::DeletedSelectedManipulatorPoints. Updated imports in document_message_handler.rs to get the correct types for messages emitted from DocumentResponse::DeletedSelectedManipulatorPoints match case in process_message().

* Removed useless import. Capitalized comments for style consistency.

* Updated messages emitted to clear Properties panel by emitting LayoutMessage::SendLayout's instead, which update the backend widget state

* Revert inclusion of unused imports
