[dogfooding][cleanup] Use new StringBuffer -> StringBuilder
cleanup for tests.model
To ensure that the new JDT cleanup works correctly for clients we should
run it also on our own code base. This help to ensure that the cleanup
works fine and helps us to cleanup our own code base.
From the commit message of the cleanup:
- create a cleanup to replace usage of StringBuffer with
StringBuilder. The two are equivalent, but StringBuffer is
thread-safe and synchronized which makes it slower than
StringBuilder which was introduced in Java 1.5.
To avoid API changes, we should only use the local variable change.
