[Issue 2046] NPE in OpenAPIV3Parser.read(String, List<AuthorizationValue>, ParseOptions)

[garydgregory]

Issue: #2046
PR: #2047

java.lang.NullPointerException: Cannot invoke "java.util.List.iterator()" because the return value of "io.swagger.v3.parser.core.models.SwaggerParseResult.getMessages()" is null
	at io.swagger.v3.parser.OpenAPIV3Parser.read(OpenAPIV3Parser.java:125)
	at ...
	at java.base/java.lang.reflect.Method.invoke(Method.java:568)

The test is convoluted because the real test would be in the main parser module plus a dependency on this module, which one cannot do due to circularity, but, note that the NPE and fix are "real" and have been tested in production on my end.
