Previously linked Cfx.re account still shows up in settings

[roentgenium-cfx]

After unlinking your Cfx.re account from FiveM, your account name still shows up under ‘Connected accounts’ in the settings menu

Steps to reproduce:

• Link Cfx.re account in FiveM
• Close FiveM
• Unlink account under ‘Apps’ in your Cfx.re account settings
• Open FiveM

Your account will no longer be linked in-game, but your username will still appear as connected in the settings menu.
