BasicTest.testTemp(true) test case will run jpackage command with --temp parameter referring to a non-existing directory.

BasicTest.testTemp(fale) test case will run jpackage command with --temp parameter referring to an existing empty directory.

Both test cases will rerun the same jpackage command line making the --temp paraterm refer to a non-empty temp directory. This run is expected to fail.

It will be four jpackage runs in total. Two "expected-to-fail" runs are identical.

Rework this test case to run jpackage three times:
1. --temp referring to a non-existing directory.
2. --temp referring to an existing empty directory.
3. --temp referring to an existing non-empty directory (expected to fail).
