b-field: message slot is ignored if horizontal is used

[tjeerdbakker38]

Overview of the problem

Buefy version: 0.1.4
Vuejs version: 3.5.4
OS/Browser: Linux/Chromium

Description

If you provide a b-field with a message slot while the horizontal property is set, the message slot is ignored. If horizontal is not set, the message slot is used for any messages below the field.

Steps to reproduce

<b-field
  label="label"
  message="message"
  horizontal
>
  <template #default>
    <b-input></b-input>
  </template>
  <template #message="props">
   This is ignored
  </template>
</b-field>

Expected behavior

The field should be rendered with "This is ignored" as message below the field

Actual behavior

The field is rendered with "message", which means the message slot is ignored
