Translate choice_attr labels for correct matching

[limenet]

Say a form has this field:

choices:
  E-Mail: 'email'
  Phone: 'phone'
choice_attr:
  Phone:
    data-icon: 'i-contact'
  E-Mail:
    data-icon: 'i-email'

And the following translation table:

key	value
E-Mail	E-mail

Then the form is translated as:

choices:
  E-mail: 'email'
  Phone: 'phone'
choice_attr:
  Phone:
    data-icon: 'i-contact'
  E-Mail:
    data-icon: 'i-email'

Which results in this JSON:

"choices":[
  {
    "label":"E-mail",
    "value":"email",
    "data":"email",
    "attr":[
      
    ],
    "labelTranslationParameters":[
      
    ]
  },
  {
    "label":"Phone",
    "value":"phone",
    "data":"phone",
    "attr":{
      "dataIcon":"i-contact"
    },
    "labelTranslationParameters":[
      
    ]
  }
]

This is caused by the non-matching labels in choices (E-mail) and choice_attr (E-Mail) after the partial translation.

Once the "labels" in choice_attr are translated as well, both choices have the attribute set correctly:

"choices":[
  {
    "label":"E-mail",
    "value":"email",
    "data":"email",
    "attr":{
      "dataIcon":"i-email"
    },
    "labelTranslationParameters":[
      
    ]
  },
  {
    "label":"Phone",
    "value":"phone",
    "data":"phone",
    "attr":{
      "dataIcon":"i-contact"
    },
    "labelTranslationParameters":[
      
    ]
  }
]

Looks good, thanks 👍

Functional test also OK
