Fixed an issue where some tests were not running.

[k163377]

As shown below, by default maven-surefire-plugin only runs tests that match certain naming conventions.

By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:

• "**/Test*.java" - includes all of its subdirectories and all Java filenames that start with "Test".
• "**/*Test.java" - includes all of its subdirectories and all Java filenames that end with "Test".
• "**/*Tests.java" - includes all of its subdirectories and all Java filenames that end with "Tests".
• "**/*TestCase.java" - includes all of its subdirectories and all Java filenames that end with "TestCase".

On the other hand, this repository contains several classes that do not match this naming convention.
For example, the following were detected in #899 (comment)
https://github.com/FasterXML/jackson-module-kotlin/blob/2.19/src/test/kotlin/com/fasterxml/jackson/module/kotlin/test/github/failing/Github242.kt

Therefore, the configuration has been modified so that all tests included in the package are executed.

This test was failing due to the different order of properties in the serialization result.
This was removed as a superfluous test case since there was no need to verify the order of the properties and the necessary verification could be done elsewhere.
