Scale command validation issues

[Dids]

Just tried using the now scale command, and could've sworn I saw now scale 1 being used in the Zeit Day stream, but that actually throws an error:

> Error! Unknown error: TypeError: id.replace is not a function
TypeError: id.replace is not a function
    at deployments.find.d (/thebox/home/travis/build/zeit/now-cli/bin/now-scale.js:145:16)
    at Array.find (native)
    at run (/thebox/home/travis/build/zeit/now-cli/bin/now-scale.js:143:29)
    at process._tickCallback (internal/process/next_tick.js:103:7)

Naturally this should complain about the syntax, not throw an error.

Using the correct syntax (now scale <id/domain/alias> 1) worked fine.
