BUG: Removed CLI tests from install package

They caused printing of these warning messages:
When loading module "CLIEventTest" , the dependency "CLI4Test" failed to be loaded.
When loading module "TwoCLIsInARowTest" , the dependency "CLI4Test" failed to be loaded.
When loading module "TwoCLIsInParallelTest" , the dependency "CLI4Test" failed to be loaded.

The problem was that the testing CLI modules that they required was not included in the package. It makes the most sense to not include these low-level tests in the installation package at all.

Note that Slicer tests that are run with --disable-cli-modules may still print similar messages for scripted or loadable modules that rely on CLI modules.
