[Issue] 🐛 Issue 72: Order of Syndicated Links

When there is a manual Syndicated Link added and then Bridgy adds syndication links, the ones added by Bridgy are prefixed to existing content instead of being appended.
Scenario: I added a manual syndicated link to Letterboxd, and then published to FB and Twitter using Bridgy. The FB and Twitter links appear before the Letterboxd link. I feel that since it is a movie post, I would want Letterboxd to appear first. I suppose this would apply to other scenarios like a Foursquare or Instagram.

Not sure if this is a Bridgy issue or Syndicated Links issue.
