[SPARK-42187][CONNECT][TESTS] Avoid using
RemoteSparkSession.builder.getOrCreate in tests
### What changes were proposed in this pull request?
This PR proposes to use `pyspark.sql.SparkSession.getOrCreate` instead of
`pyspark.sql.connect.Sparksession.builder.getOrCreate`.
### Why are the changes needed?
Because `pyspark.sql.connect.Sparksession.builder.getOrCreate` is supposed
to be internal, and it does not have the unified handling of the Spark sessions
for both PySpark session and Spark Connect sessions.
### Does this PR introduce _any_ user-facing change?
No, test-only.
### How was this patch tested?
Unittests fixed.
Closes #39743 from HyukjinKwon/cleanup-test.
