No spaces in NLU extracted slots

[kercos]

Describe the bug When I define a slot with spaces (e.g, i want to book a flight to [new york]) the system correctly detects them but in {{event.nlu.slots.slotname.value}} I see them without spaces (newyork).

This issue has been addressed by iicky in the forum (https://help.botpress.io/t/no-spaces-in-nlu-extracted-slots/2602). User Estyms suggested to solve it with an ad hoc function parsing again the sentence to find the slot, but I don't this this is a very elegant solution. I believe this is a bug of the NLU module and should be solved internally.

To Reproduce Steps to reproduce the behavior:

1. In NLU, define a new entity toCity with rome, new york, toronto, paris
2. Define a new intent Fights and add new sentences (including i want to flight to new york)
3. Create a new slot for this intent with type toCity
4. Tag all cities in the sentences with this slot
5. In the emulator type the sentence i want to flight to new york and look at the debugging info.

Expected behavior event.nlu.slots.toCity.value should be new york instead of newyork
