Per Tony's suggestion, adding a random string to the CSS version did the trick. Here's the code I used to do that.
First this code to generate the random number.
// get theme version
function cd_get_version() {
$theme_data = wp_get_theme();
return $theme_data->Version;
}
$theme_version = cd_get_version();
global $theme_version;
// get random ...

No, you can't use set_post_thumbnail() to remove the post thumbnail. The function you need is delete_post_thumbnail().
// Both of these work.
delete_post_thumbnail( $post->ID ); // pass the post ID
//delete_post_thumbnail( $post ); // or post object

You need to use get_field() function instead. It will RETURN the value instead of printing.
So, your code will be:
soliloquy( get_field( 'slider' ) );

if you prefer to retrieve the value from wpcf7 instead of the $_POST array, you can use the following. this is similar to how to retrieve the posted data. just use get_meta instead of get_posted_data:
$submission = WPCF7_Submission :: get_instance();
$submission->get_meta('container_post_id');
