Slot value is not extracted if optional

[mathquis]

For ASR result:

read me the hound of the baskervilles in the bedroom

With:

[playBook]
read me ($audiobook-book-name){book} ($assistant-zones){zone}

I get both book and zone slot extracted by the NLU.

With

[playBook]
read me ($audiobook-book-name){book} [ ($assistant-zones){zone} ]

I get only book although zone is present.

Hope this helps.

Should be fixed in 2.4.13
