cli/command: move TestExperimentalCLI to cli/config

This test was only testing whether we could load a legacy config-file that
contained the "experimental" (experimental CLI) option. Experimental cli
options are disabled since 977d3ae (20.10),
and now enabled by default, but we should not fail to start the cli if the
config-file contains the option.

Move the test to the config package, as it doesn't need the cli for this.
