Do not change package when non-recursive

[timtebeek]

Add unit test as reported via Slack by @BhavanaPidapa; update precondition to evaluate recursive boolean for package declaration too.

Hey Tim,

Below is the test case where changes to com.sun.net.ssl.internal.* are not expected. Please refer to the attached screenshot.

@Test
void excludePackageTest() {
    //language=java
    rewriteRun(
      spec -> spec.recipe(new ChangePackage(
        "com.sun.net.ssl",
        "javax.net.ssl",
        false
      )),
      java(
        """
          package com.test;
          import com.sun.net.ssl.internal.*;
          import com.sun.net.ssl.HostnameVerifier;
          class Test {
           public com.sun.net.ssl.HostnameVerifier hv;
              void exampleMethod() {
              }
          }
          """,
        """
          package com.test;
          import com.sun.net.ssl.internal.*;
          import javax.net.ssl.HostnameVerifier;
          class Test {
           public javax.net.ssl.HostnameVerifier hv;
              void exampleMethod() {
              }
          }
          """
      )
    );
}

This is an interesting case: we first and separate evaluate a precondition to determine if we need further changes; that precondition resolves to true due to the presence of com.sun.net.ssl.HostnameVerifier; then we unconditionally change any package references in the actual visitor, whereas we should probably still take into account there whether we should do so recursively.

Maybe fixed by https://github.com/openrewrite/rewrite/pull/4942? Not sure, as the work I did was for YAML.
