[Bug & Enhancement] Obliviance to the path of database

[lifehome]

Overview

With unchecking the box of "remembering" last used database, KeePassXC should not remember what was the last database it opened, nor it should remember where it locates.

However, as of KeePassXC 2.6.6 (macOS), when a user locks and closes a database, regardless the storage destination is a removable device, or local home directory, KeePassXC will open the last location where the database was located in.

This is not a privacy-oriented design, and violates the meaning of unchecking the configuration boxes shown above.

Steps to Reproduce

1. Open a database in KeePassXC 2.6.6
2. Close the database, or just quit KeePassXC
3. Now reopen the program and click "Open Database" button, and you will be directed to the last location the database was located in.

or

1. Open a database in KeePassXC 2.6.6
2. Close the database, or just quit KeePassXC
3. cat ~/Library/Caches/KeePassXC/keepassxc.ini and see the saved LastDir is the actual location of our last opened database location

Expected Behavior

KeePassXC should open either the current user home directory, or anywhere else.

Actual Behavior

KeePassXC opened the last known location of the database.

Context

KeePassXC - 2.6.6
