Remove warnings

Is your feature request related to a problem? Please describe: It is related to remove warnings in the code

Describe the solution you'd like:
We can remove some unused parameters in src/Serilog.Ui.SqliteDataProvider/SqliteQueryBuilder.cs functions.

string schema

We also can remove the second argument from the method Guard.Against.Null() because it hides the caller information. The files with that warning are src/Serilog.Ui.Web/Endpoints/SerilogUiAppRoutes.cs, src/Serilog.Ui.Web/Endpoints/SerilogUiAppRoutesDecorator.cs and src/Serilog.Ui.Web/Extensions/ServiceCollectionExtensions.cs

Guard.Against.Null(Options, nameof(Options))
