fix: make sure model event in v-model is the first to avoid regression

[ShGKme]

☑️ Resolves

• Regression from: feat: forward compatibility with v9 on v-model props/events #6172
• Fixes: [Bug]: Changing TaskProcessing selects wrong provider nextcloud/server#49335
• fix(settings): Add nextTick to saveChanges nextcloud/server#49343

v-model event was fired later than the original like input or update:value. As a result - old event handlers were executed before the model value is actually updated

Solution: trigger the event defined in the model option first. Also, update:modelValue should be before update:model-value, but it was correct

To test: log model value from value update event from any component with v-model

<NcSelect
  v-model="value"
  @input="log('input', value)"
  @update:model-value="log('model-value', value)"
  @update:modelValue="log('modelValue', value)"
/>

<NcInputField
  v-model="value"
  @update:value="log('value', value)"
  @update:model-value="log('model-value', value)"
  @update:modelValue="log('modelValue', value)"
/>
