incorrect error when class with parameters follows trait in parents

[anatoliykmetyuk]

minimized code

scala> trait Bar
// defined trait Bar
scala> enum B(x: Int) {
     |   case Foo extends Bar with B(10)
     | }
2 |  case Foo extends Bar with B(10)
  |                            ^^^^^
  |                            class B is not a trait
2 |  case Foo extends Bar with B(10)
  |                   ^
  |            missing argument for parameter x of constructor B: (x: Int): B

expectation

The second error message is wrong as we are definitely not missing an argument for B's constructor.

this also exploits that checking for enum parent only checks first parent as now the errors include

2 |  case Foo extends Bar with B(10)
  |       ^
  |       enum case does not extend its enum class B

minimise to

trait Foo
class A(x: Int)
class Bar extends Foo with A(10)

giving

4 |class Bar extends Foo with A(10)
  |                           ^^^^^
  |                           class A is not a trait
4 |class Bar extends Foo with A(10)
  |      ^
  |      missing argument for parameter x of constructor A: (x: Int): A

if Foo is a class then the second error is dropped
