Issue Description:

Adding // swift-format-ignore inside a case in a switch statement causes the linter to crash with the following message:

Fatal error: At least one .break(.open) was not matched by a .break(.close): file SwiftFormatPrettyPrint/PrettyPrint.swift, line 689

Example code that causes the crash is below (running swift-format -r -m lint .):

class Test {
 enum FooBar: String {
     case foo
     case bar
 }
 
 func myFunc(_ val: FooBar) {
     switch val {
     case .foo:
         // swift-format-ignore
         print("Foo")
     case .bar:
         print("Bar")
     }
   }
}
