Restarting vscode while the extension is starting up can remove databases. #1489
Description
Describe the bug
Restarting the extension before all databases have been reloaded means we lose the databases that haven't been loaded yet.
Version
CodeQL extension version: 1.6.11
CodeQL CLI version: 2.10.3
Platform: linux x64
To reproduce
- Start vscode with the extension and add some large databases.
- Restart vscode.
- Close it while some but not all databases have been loaded.
- Reopen it and notice that the databases are missing.
Expected behavior
The databases that weren't loaded were loaded the next time.
