Prompt users to configure tasks

Fixes #6525
Fixes #1017

- adjust the `run task` to display an item which prompts users to configure tasks when
no tasks are currently available.
- adjusts the `run build task` to display an item which prompts users to configure
tasks when no tasks are currently available.
- adjusts the `run test task` to display an item which prompts users to configure
tasks when no tasks are currently available.
