`PathResourceResolver.getResource()` does not log warning if `Resource#getURL()` throws exception

[matthiaskraaz]

If ServletContextResource.getURL() throws a FileNotFoundException because ServletContext.getResource(String) returns null, then org.springframework.web.servlet.resource.PathResourceResolver.getResource(String, Resource) does not log a warning as intended.

Hi @matthiaskraaz,

Congratulations on reporting your first issue for the Spring Framework! 👍

I have a fix prepared locally, and we'll make sure to include it in the next release.
