feat: add option to add diary entry even for non-active task

[srl295]

should be able to pass an option to the taskwarrior plugin to get a non-active task.

right now, mourt only looks at the active task.

scenario:

$ task start 123
fix all the things started.
$ ### (do stuff)
$ task stop 123
$ mourt -m 'Hey, i fixed all the things'  --plugin-args '123'
