Errors when updating monix from `3.0.0-RC1` to `3.0.0-RC2-840c090`

error with 3.0.0-RC2-840c090

when updating monix from `3.0.0-RC1` to `3.0.0-RC2-840c090`, there were warnings but also some errors like:


code:
```
trait ContextAware {
  def runInContext[A](context: Context)(task: Task[A])(implicit scheduler: Scheduler): CancelableFuture[A] =
    (Context.write(context) >> task).executeWithOptions(_.enableLocalContextPropagation).runAsync
}
```
(used to execute a `Task` with a certain `Context` when a `Future` is expected)

```
[error] .../Context.scala:48:90: missing argument list for method runAsync in class Task
[error] Unapplied methods are only converted to functions when a function type is expected.
[error] You can make this conversion explicit by writing `runAsync _` or `runAsync(_)(_)` instead of `runAsync`.
[error]     (Context.write(context) >> task).executeWithOptions(_.enableLocalContextPropagation).runAsync
