Previously, a NullPointerException would occur when WebFluxTags
attempted to create a method Tag for a request with a non-standard
method.

This commit updates WebFluxTags to use getMethodValue(), which will
never return null, rather than getMethod(), which may return null,
when determining the tag's value for the given request.
