Can we remove scala-reflect requirement in XtensionTokenName?

[olafurpg]

See https://github.com/olafurpg/scalafmt/issues/492

For some reason, parsing this invalid source requires scala-reflect.

object A {
  <.section(render(props)
}

The root cause is XtensionTokenName:

scalameta/scalameta/tokens/src/main/scala/scala/meta/internal/tokens/package.scala

Lines 7 to 17 in ca2b2d1

	implicit class XtensionTokenName(token: Token) {
	def name: String = {
	import scala.reflect.runtime.{universe => ru}
	object TokenReflection extends {
	val u: ru.type = ru
	val mirror: u.Mirror = u.runtimeMirror(classOf[Token].getClassLoader)
	} with scala.meta.internal.tokens.Reflection
	import TokenReflection._
	val mirror = ru.runtimeMirror(classOf[Token].getClassLoader)
	mirror.classSymbol(token.getClass).asLeaf.tokenName
	}

It would be fantastic if I could drop the dependency on scala-reflect in scalafmt ^^
