Fix bug where a single image path fails

[jbarciauskas]

• Fix bug where a single image path fails
• Slight improvement to error handling
• Remove support for passing in an image directly, only support image paths

The following example currently results in a 400 error in the current code, and is fixed in this PR:

bs_post(
    text = 'Test photo.', 
    images = c('~/Downloads/profile-circle.jpg'),
    images_alt = c('test alt'))

Thanks @jbarciauskas. I gave this a quick look and it seems to be just a bug with unlisting a single entry (that is no longer needed). It's removed in 3805cb5. This fix avoids removing functionality vs the PR. Does that fix it for you?

  images = c(fs::path_package('bskyr', 'man/figures/logo.png')),
  images_alt = c('test alt: this is the same logo'),
