[FIX]: set initial state properly for password modal

[imLinguin]

Since we are loading password from backend asynchronously we need to add useEffect that will react to those changes. It's a small but annoying bug

Use the following Checklist if you have changed something on the Backend or Frontend:

• Tested the feature and it's working on a current and clean install.
• Tested the main App features and they are still working on a current and clean install. (Login, Install, Play, Uninstall, Move games, etc.)
• Created / Updated Tests (If necessary)
• Created / Updated documentation (If necessary)
