Backup Project fails to honor the setting for Saves in Directories preferences

Bug description

Backup Project fails to honor the setting for Saves in Directories preferences - but Save Project and Save Project As both properly honor this setting.

Steps to reproduce

1. clear the audacity settings folder
2. launch Audacity
3. Use any/all of the three Save Project commands: Save Project, Save Project As and Backup Project
4. Observe: for all three: the default Save location is offered: C:\Users<username>\Documents\Audacity
5. Abort the Save
6. In Directories prefs set the location for Save to be Desktop
7. Use Save Project and Save Project As
8. Observe: the location offered is Desktop (expected behavior)
9. Abort the Save
10. Use Backup Project
11. Observe: incorrectly the location offered remains the Audacity default: C:\Users<username>\Documents\Audacity

Expected behavior

Backup Project should honor the setting for Saves in Directories preferences (as do Save Project and Save Project As

Actual behavior

Backup Project fails to honor the setting for Saves in Directories preferences

Audacity Version

3.3.3 and latest alpha test build for 3.4.0: audacity-win-3.4.0-alpha-20230719+aa59545-x64-msvc2022
and @vsverchinsky 's latest branch build for new Export: audacity-win-3.4.0-alpha-20230724+d3d98a4-x64

Operating system

Windows - but assume all OS

Additional context

Discovered while testing @vsverchinsky 's latest branch build for new Export, testing Timer Record - leading me to explore the save commands.

Testing on W10 with latest 3.4.0 master: audacity-win-3.4.0-alpha-20231016+32cf29e-x64-msvc2022

This remains the case, so I have added an advice div to the appropriate page in the Manual:

Testing shows that this a regression on 3.3.3

@dozzzzer

Testing on macOS 12.7 Monterey with latest 3.4.0 Beta

This also fails on Mac - the offered location is also the default Audacity location on Mac
