Parse dashed command names properly

[kitsonk]

Type: bug

The following has been addressed in the PR:

• [X] There is a related issue
• [X] All code matches the style guide
• [X] Unit or Functional tests are included in the PR

Description:

This PR fixes issues when a command has a dash in it's name. Commands like cli-foo-bar-baz will be parsed as a group of foo and a name of bar-baz. Previously, these were being parsed as foo-bar and baz.

This will mean that group names cannot be dashed.

Resolves #142
