Wrong testify dependency used

[rustyx]

This module uses github.com/test-go/testify which is an obsolete fork of github.com/stretchr/testify.

Consequently pulling this module in go.mod transitively pulls that obsolete dependency, which messes with auto-completion (risk of accidentally selecting the wrong package for assert and require).

require (
    github.com/test-go/testify v1.1.4 // indirect
    github.com/trustelem/zxcvbn v1.0.1
)

Thus hereby a request to use the correct dependency for testify.
