Nested Components layout broken

[dhakehurst]

Describe the bug
Layout does not work for nested components and ports

To Reproduce
Works fine:

@startuml
!pragma layout smetana
component X {
   port a
   port b
   component Y
}
@enduml

Layout breaks - inner component lost from diagram:

@startuml
!pragma layout smetana
component X {
   port a
   port b
   component Y {
   }
}
@enduml

Layout breaks - inner component displayed, but ports on outer component missaligned:

@startuml
!pragma layout smetana
component X {
   port a
   port b
   component Y {
     port c
   }
}
@enduml
