Add Jackson test dep & relax negotiation test

Add com.fasterxml.jackson.core:jackson-databind as a test dependency and adjust WebMvcAutoConfigurationAllEnabledTest to be less brittle. The test now asserts the strategies list is non-empty and iterates to find a ParameterContentNegotiationStrategy (asserting its parameter name is "p") instead of relying on an exact size and specific ordering.
