Add getUniqueJobParametersBuilder() method in JobLauncherTestUtils

[spring-projects-issues]

jojoldu opened BATCH-2847 and commented

JobLauncherTestUtils often uses the getUniqueJobParameters method.
But it seems a bit cumbersome to use this method with other JobParameters.
In the same case, I use it like this:

new JobParametersBuilder(jobLauncherTestUtils.getUniqueJobParameters())
.addString()
.addDouble()

I want to make this convenient.

jobLauncherTestUtils.getUniqueJobParametersBuilder()
.addString()
.addDouble()

What do you think?
