fix(tasks): update how addonDatasetProvider ready state is set

[pedrobonamin]

Description

Fixes an issue in which when trying to create the addon dataset through the tasks plugin, this was not being created.
This is caused because the ready: true value was only set if the dataset name exists.

By updating this, the addon provider will return ready:true after fetching the dataset, either it exists or not.
This flag is used by <TasksAddonWorkspaceProvider /> to decide if it should or not create the addon dataset.
