False positive with Style/IfWithBooleanLiteralBranches and nonzero?

[erwanlr]

The nonzero? method returns self if num is not zero, nil otherwise, and not a boolean. Causing false positive with the Style/IfWithBooleanLiteralBranches cop with code such as val.nonzero? ? true : false

---

Expected behavior

The cop should not flag statements such as val.nonzero? ? true : false

Actual behavior

 Style/IfWithBooleanLiteralBranches: Remove redundant ternary operator with boolean literal branches.
      NS::Browser.get(url(path)).code.nonzero? ? true : false

Steps to reproduce the problem

Run the cop against code like val.nonzero? ? true : false , for example https://github.com/wpscanteam/CMSScanner/blob/master/lib/cms_scanner/web_site.rb#L74
