Tab complete executes commandline command already.

[w1ll-i-code]

Describe the bug

When using tab-complete in icingacli director, the command will sometimes get already executed.

To Reproduce

1. Type icingacli director host create test --check_command dummy -- into the commandline
2. Without hitting enter, trigger the tab-completion
3. Notice that the host has been created already.
4. Hitting tab-complete again will print an error that the object already exists.

Expected behavior

The object should only ever be created if the command is actually run.
