Investigate how to make VSCode properly reload configs

[maxyu1115]

Currently, while an attempt has been made to reload the vscode configs, it doesn't actually work.

While the detection by onDidChangeConfiguration properly triggers the event, my attempt reloading the config with vscode.workspace.getConfiguration doesn't read in the newer configs.

Is there a way to fix this? If not, we need to create a warning/notice for users to reload.

Also we probably should modify line

git-backup-sync/src/extension.ts

Line 16 in df71da0

extension.loadConfig();

to have a if (event.affectsConfiguration('git-backup-sync')) check as well.

Mysterious forces are in play, failing to reproduce this... The current loadConfig should be working in most cases at least.

Worst case, we will need to add lines to either restart the extension host vscode.commands.executeCommand('workbench.action.restartExtensionHost');, or reload the window vscode.commands.executeCommand('workbench.action.reloadWindow');. Both will have performance implications and potentially cause issues when working with a remote ssh vscode session.

This bug might only trigger when the autobackup is enabled. We'll tackle this again after #20 is fixed.
