Subject: [PATCH] fix(availability-sync): handle resolution check for
 single-server setups (#2334)

PR #1543 introduced resolution checking to check 4k from non4k media when users have both server
types configured with the same service. Howerver, this causes false deletions for users with only a
single non4k service when radarr upgrades file to 4k resolution. This fix only applies resolution to
checking when both 4k and non4k servers are configured. Otherwise then if file exists then it counts
as available
