fix: add safety check for command.clone when cmd does not have args

[emilyrohrbough]

While pulling in the logGroup changes into within in the 10.x branch, I noticed two consistent command failures with the following error:

The test flow could be summarized like:

cy.get('modal').as('modalAlias').within(() => {}) // within using log group

// do something 

cy.get('@modalAlias') // command replay is triggered which includes replaying the end-logGroup command

When a command is replayed, it's cloned and injected into the command queue.
When the command is cloned, it pull sanitize the commands args list to pull forward an create a new command. Generally commands have args, but because the injected end-logGroup command did not have args passed, it was undefined and caused this error.

This check just ensures commands lacking args can successfully be cloned.
