Before the test used the `help` command to verify that access to the
shell is present. While this does have the benefit of not requiring a
custom command, it does have some robustness issues:
- When new default commands get added, this test will fail
- When the help message of a command gets reworded, the test will fail
- When the order of commands in the test will change, the test will fail
- Note that with the XFA based `SHELL_COMMAND()` macro, we do not
guarantee any particular order. Specifically, the order can change
with implementation details.
