Passing arguments to Ngrok broken in v.4.8.0

[kiritokatklian]

Description

v4.8.0 breaks passing arguments like --domain with the valet share command. Only tested with Ngrok. For now I've downgraded back to v4.7.1, since it works in this version

Steps To Reproduce

$ valet share-tool ngrok
$ valet share --domain=custom.domain

Diagnosis

N/A

It seems like this line has to have != instead of ==.
