Bug description:
  [Impact]
  Thunderbolt updates posted to LVFS fail to install

  [Test Case]
  On an XPS 9360 (Only system currently published with TBT FW update).
  0) Restart fwupd.service or restart machine.
  1) fwupdmgr refresh
  2) fwupdmgr update
  3) Observe no errors

  If TBT update already applied, please manually download from LVFS and follow these steps
  1) fwupdmgr install <blah.cab> --allow-reinstall

  [Regression potential]
  Low, only affects Dell machines

  [Other info]
  fwupd 0.9.7 has support for doing thunderbolt firwmare updates.
  Thunderbolt controllers will go to sleep if not in use (No TBT device connected).
  fwupd 0.9.7 has a special way to wake up dell TBT controllers, that's where this problem is.
  It doesn't happen if TBT device connected when update is run
  fwupd 1.0.2 (in bionic) will not be affected.  it wakes TBT controller using a different interface over WMI
