### Motivation
<!-- Explain here the context, and why you're making that change. What is
the problem you're trying to solve. -->
Each of the tests below were written with the assumption that the json
key-value pairs would have a deterministic order (by comparing json results vs
hard coded strings). The order of key-value pairs is not guaranteed in [JSON
files](https://www.json.org/json-en.html) or [JSON
objects](https://docs.oracle.com/javaee/7/api/javax/json/JsonObject.html),
though. As a result, the ordering can change due to different environments
producing the contents in different orders despite the logical contents being
the same. Since each of the tests below compare the raw strings/trees "as-is",
harmless re-ordering could flip the test from pass to fail despite the data
being semantically the same.

### Modifications
<!-- Describe the modifications you've done. -->
We no longer compare raw strings "as-is" with ```Assert.assertEquals```.
Instead, we compare the json structures with
```JsonAssert.assertEquals(expectedJson, actualJson, JSONCompareMode)``` which
parses both inputs into JSON trees. It treats these JSON trees as unordered
collections of key-value pairs when determining if they are equal so
differences in property order no longer matter. This ensures the tests pass
consistently, even when the serializer outputs fields in a different order.
In essence, these changes keep the spirit of the original tests while
eliminating failures caused solely by allowed (but previously unexpected)
reordering.

### Matching PR in forked repository
PR in forked repository: https://github.com/LucasEby/pulsar/pull/3
<!--
After opening this PR, the build in apache/pulsar will fail and instructions
will
be provided for opening a PR in the PR author's forked repository.
apache/pulsar pull requests should be first tested in your own fork since
the
apache/pulsar CI based on GitHub Actions has constrained resources and quota.
GitHub Actions provides separate quota for pull requests that are executed
in
a forked repository.
The tests will be run in the forked repository until all PR review comments
have
been handled, the tests pass and the PR is approved by a reviewer.
