fix: only try to get ipfs if argv is present (#2504)

Sometimes you've done something silly like required a module that isn't installed or called a method that isn't a property of an object in which case `argv` won't have a value, causing an unrelated error to appear.

This PR just makes sure `argv` has a value before trying to access `argv.getIpfs`
