When applying Border tokens we always apply color as a hex, instead of style when available

[six7]

Base this on release-133.

To reproduce:

• Create a color token calledblack with a value of #000000
• Hit Create styles so there's a color style of black
• Create a border token called borderDefault with a value of

{
  "value": {
    "width": "3px",
    "color: "{black}"
    "style": "solid"
  }

When you now apply that border token on a layer, it is expected that the color style is applied, and only when we do not find that color style do we apply the hex value.

Instead, we currently apply the hex value.
