Server Redirect Notices and User Redirect Notices should be independent

As explained on IRC:

[12:15:49] <PeGaSuS> justJanne: I found a weird behaviour in Quasseldroid in my phone (Huawei P20 Lite). Menu > Client Settings > Message Redirection > Enable "Redirect User Notices"
[12:15:49] <PeGaSuS> Tap the back arrow. Menu > Client Settings > Message Redirection > "Redirect User Notices" and "Redirect Server Notices" will be enabled.
[12:15:49] <PeGaSuS> Disable "Redirect Server Notices", tap back arrow, Menu > Client Settings > Message Redirection > All redirects will be disabled
[12:17:10] <PeGaSuS> shouldn't "User Notices" and "Server Notices" be independent?
