Task macros that contain more than 768 characters cannot be saved as task

[michitux]

Steps to reproduce:

1. Insert a task macro
2. In the content, insert more than 768 characters, e.g., "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi. Aenean vulputate eleifend tellus. Aenean leo ligula, porttitor eu, consequat vitae, eleifend ac, enim. Aliquam lorem ante, dapibus in, viverra quis, feugiat a, tellus. Phasellus viverra nulla ut metus varius laoreet. Quisque rutrum. Aenean imperdiet. Etiam ultricies nisi vel augue. Curabitur ullamcorper ultricies nisi. Nam eget dui. Etiam rhoncus. Maecenas tempus, tellus eget condimentum rhoncus, sem quam semper libero, sit amet adipiscing sem neque sed ipsum. Nam quam nunc, blandit ve".
3. Save the document.

Expected result:

The task's document is saved, and no error is logged.

Actual result:

A warning WARN i.TaskMacroUpdateEventListener - Failed to retrieve the document that contains the Task Object with id [xwiki:journal.2024.01.15.Tasks.Task_0.WebHome]: [PSQLException: ERROR: value too long for type character varying(768)]. is logged and the task's document is not saved accordingly. This is because the task macro's content is saved as name and this field only supports 768 characters. The log message's origin is most likely

application-task/application-task-default/src/main/java/com/xwiki/task/internal/TaskMacroUpdateEventListener.java

Line 245 in 20b6863

logger.warn("Failed to retrieve the document that contains the Task Object with id [{}]: [{}].",

- the message is quite misleading, as this about updating/creating a document and not about loading a document.

Fixed, thanks @michitux for the investigation.
