* feat(cli): add test for delete
This adds a new test for the `delete` command to ensure it works as
expected when provided the correct args.
* fix(cli): use ExecuteC() to match Cobra
This modifies the `cli.Root().Execute()` to `cli.Root).ExecuteC()` to
match the default behavior of Cobra. We do this so errors will always
print the "run --help" line.
* feat(cli): add WithoutParameters test for delete
This adds a new test to the `delete_test.go` suite to ensure the correct
behavior occurs when `delete` is called without an argument.
* fixup! feat(cli): add WithoutParameters test for delete
* refactor(cli): show --help error message on main
This adds an error message which shows when there is an error with any
commands called to improve the UX.
* fixup! refactor(cli): show --help error message on main
* refactor(cli): handle err with FormatCobraError
This adds a new helper function called `FormatCobraError` to `root.go`
so that we can colorize and add "--help" message to cobra command errors
like calling `delete`.
* refactor(cli): add root_test.go, move delete test
