Deserialization of Throwables with PropertyNamingStrategy does not work

[cowtowncoder]

(note: follow up to #3275 )

It looks like following test would fail:

    public void testDeserializeWithNamingStrategy() throws IOException {
        final ObjectMapper mapper = JsonMapper.builder()
                .propertyNamingStrategy(PropertyNamingStrategies.UPPER_CAMEL_CASE)
                .build();
        Exception ex = mapper.readValue(a2q(
                "{'Message':'Message!, 'Cause':{}}"
                ),
                Exception.class);
        assertNotNull(ex);
    }

since naming strategy is not considered when constructing deserializer for Throwable types.
It should work.

Solved for the most part: specifically for strategies that only change casing (like UPPER_CAMEL_CASE).
Some issues likely still remain for other kinds (kebab, snake style) wrt ThrowableDeserializer (whereas StackTraceElementDeserializer works fine with them) but those will need to be handled with more work
