`Storage` does not work without `ThemeSwitching`

[xperiandri]

Current behavior

Cannot activate IKeyValueStorage because of missing ISettings

Expected behavior

Calling UseStorage adds all required services

How to reproduce it (as minimally and precisely as possible)

var host = UnoHost.CreateDefaultBuilder()
    .UseSerialization()
    .UseStorage()
	.Build()
host.Services.GetRequiredDefaultInstance<IKeyValueStorage>()
