Check for group presence after full initialization (#1839)

Browse Source 
Fixes #1831

By moving the check for help group existence to "ExecuteC()" we no
longer need groups to be added before AddCommand() is called.  This
provides more flexibility to developers and works better with the use
of "init()" for command creation.

### Grouping commands in help
Cobra supports grouping of available commands. Groups must be explicitly defined by `AddGroup` and set by
the `GroupId` element of a subcommand. The groups will appear in the same order as they are defined.
If you use the generated `help` or `completion` commands, you can set the group ids by `SetHelpCommandGroupId`
and `SetCompletionCommandGroupId`, respectively.
Cobra supports grouping of available commands in the help output. To group commands, each group must be explicitly
defined using `AddGroup()` on the parent command. Then a subcommand can be added to a group using the `GroupID` element
of that subcommand. The groups will appear in the help output in the same order as they are defined using different
calls to `AddGroup()`. If you use the generated `help` or `completion` commands, you can set their group ids using
`SetHelpCommandGroupId()` and `SetCompletionCommandGroupId()` on the root command, respectively.
