Support client disconnection

[SrMouraSilva]

• Disconnect show dialog
• When rotate display: WindowManager: Activity io.github.pedalpi.displayview.activity.resume.ResumeActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@433d4c08 that was originally added here
  Talvez seja por perder a referência quando faz rotate
