Minor typo fixes in output when restoring a backup

[jmynes]

I ran into a typo while using qvm-backup-restore, Exisiting --> Existing

---

This typo also appears in a few other files:
https://github.com/search?q=org%3AQubesOS%20Exisiting&type=code

• QubesOS/qubes-gui-agent-linux
  • pulse/pulsecore-0.9.21/aupdate.h
  • pulse/pulsecore-0.9.22/aupdate.h
  • pulse/pulsecore-0.9.23/aupdate.h
• QubesOS/qubes-posts
  • 2017-04-26-qubes-compromise-recovery.md

But I wasn't sure if these should be edited, or not.

There is one more place in tests to update (it's hilarious to see test checking if you got the typo right :D)

QubesOS/qubes-gui-agent-linux

* [pulse/pulsecore-0.9.21/aupdate.h](https://github.com/QubesOS/qubes-gui-agent-linux/blob/b1c52ac515556e3bb02c712d60d7105d5b98b994/pulse/pulsecore-0.9.21/aupdate.h#L50)

* [pulse/pulsecore-0.9.22/aupdate.h](https://github.com/QubesOS/qubes-gui-agent-linux/blob/b1c52ac515556e3bb02c712d60d7105d5b98b994/pulse/pulsecore-0.9.22/aupdate.h#L50)

* [pulse/pulsecore-0.9.23/aupdate.h](https://github.com/QubesOS/qubes-gui-agent-linux/blob/b1c52ac515556e3bb02c712d60d7105d5b98b994/pulse/pulsecore-0.9.23/aupdate.h#L50)

Those are imported from pulseaudio, so should remain unchanged (you may send a patch to pulseaudio project ;) )

QubesOS/qubes-posts

* [2017-04-26-qubes-compromise-recovery.md](https://github.com/QubesOS/qubes-posts/blob/05a8a728187978bf2d4a4e515f448f4180fef695/2017-04-26-qubes-compromise-recovery.md?plain=1#L286)

This shows an output of the tool at that time, should remain as is too.

Looks like they fixed it 14 years ago in pulseaudio (along with many other typos in that commit 😅 )

Thanks for the quick turnaround
