Due to the side effect on related fields that are not readonly, the value is saved
in project although not changed. Putting it readonly avoids the problem.
Fixes#26156Closes#26171
The duplication of a task crashes at the following:
`content = myPad.getHtml(path).get('html', '')`
The copy mechanism is quite cumbersome:
- In `copy` method, generate an URL of a pad which doesn't exist since
`object_id` is still undefined.
- The `create` method somehow attempts to fill in the previously created
pad thanks to `_set_pad_value`.
The logic is made simpler. The pad URL field is set as `copy=False`,
therefore the create mechanism will take care of handling the pad
creation and its synchronization.

Purpose
=======
Currently if a project doesn't use pads, the created and duplicated tasks will initialize/copy them. That could be a real issue when migrating customers if we create a task for all the existing issues, since the models have been merged.
Specification
=============
Avoid this falsy behavior. We're forced to crappy fix with a context key as the project.task model 'inherit' from pad.common.
