Subject: [PATCH] Correctly compute inputNumberDisabled when false

`input-number.vue` incorrectly calculates `inputNumberDisabled` when the prop `disabled` is set to false as well as `elForm` not existing. `inputNumberDisabled` returns `"undefined"` instead of `false` which is treated as a truthy value on `aria-disabled`.
