Make Last-Modified and If-Modified-Since headers follow the spec

Fully normalizes the baseUrl behaviour to better match how this sort of
feature works in other programs.
1. The baseUrl is always appended to paths, even the built-in `/emby`
and `/mediabrowser` paths.
2. The baseUrl is set statically at class instance creation, to ensure
it persists through changes until the next restart.
3. Configuration is normalized using a function when set, to ensure it's
in a standard `/mypath` format with leading `/`.
4. Cleans up the conditionals around default redirects. For sanity after
changing the URL, it will match *any* path that doesn't match the
current baseUrl and redirect it back to the main page (with baseUrl).
5. Adds a second method, NormalizeUrlPath, to avoid lots of `+ "/" +`
string manipulations which are unclean - we should always have a leading
slash.
6. Sets the default baseUrl to an empty string to avoid unexpected
behaviour, though this would be worked-around automatically.
7. Adds some debug logs whenever a URL is normalized, to help track down
issues with this code (if any arise).
* Fix warnings, improve performance
`QueryResult.Items` is now a `IReadOnlyList` so we don't need to
allocate a new `Array` when we have a `List` (and `Items` shouldn't need to
be mutable anyway)
* Update Providers .csproj to latest C#
* Remove extra newline from DtoService.cs
* Remove extra newline from UserLibraryService.cs
