Wildcard capitalization issues during recognition

[tetele]

Fixtures:

entities:
  - name: "Joseph"
    id: "person.jospeh"
    state: "home"
  - name: "Ada"
    id: "person.ada"
    state: "Work"
  - name: "John"
    id: "person.john"
    state: "not_home"

Sentences and tests:

lists:
  zone:
    wildcard: true
intents:
  HassGetState:
    data:
      - sentences:
          - "is anyone [<in>] [the] {zone:state}"
        response: any
        slots:
          domain: person
tests:
  - sentences:
      - "is anyone at Work"
    intent:
      name: HassGetState
      slots:
        domain: person
        state: Work
    response: "Yes, Ada"

produces

E                           AssertionError: Expected work, got Work for slot state for: is anyone at Work
E                           assert 'Work' == 'work'

I think this issue here might also be the reason why the shopping_list_item slot in the intents is always transformed to lowercase when matched.

I am sure there are use cases where ignoring upper-/lowercase make sense, but for some it produces problems (especially in other languages).

maybe this can be achieved with an optional config like preserve_case, defaulting to False?

although having a quick look at the code it doesn't seem straight forward, as casefold can change the length of the text and therefore the index of the wildcard match in the original text.
