fix "always need to unlock gesture pattern when changing library" error

Though the error was fixed, there still left another serious problem here, which damages user experience.

After set up Gesture Lock, it cannot restore its checked state, so every time resume back to Settings menu, the Gesture Lock checkbox was always unchecked.

This bug will be fixed in next PR.
这个 EXTRA_CAMERA_UPLOAD 不需要放到 SettingsManager 里面去，因为它只是一个 intent 参数，而不属于 “用户设置”。
