Minor XDGB edge cases (#1425)

This fixes 3 minor issues:

1) when the user does not specify a subcommand XDBG exits with code 0. This can be a bit confusing. Print help instead and exit with an error.
- I am open to other options. Printing to stderr and std::process:exit(1) are also pretty good choices.



2) Generate could not print help

```
$ cargo run --package xdbg -- generate -h
    Finished `dev` profile [unoptimized] target(s) in 0.19s
     Running `target/debug/xdbg generate -h`
The application panicked (crashed).
Message:  Command generate: Short option names must be unique for each argument, but '-i' is in use by both 'invite' and 'interval'

Now it can

3) Typo in `loclalhosltls`
