Bug: can not use logging with bool

[icyleaf]

Halite.logging(true).get("...")

# Or
Halite::Client.new
  logging true
end

It returns:

in src/halite/chainable.cr:390: no overload matches 'Halite::Options#with_logging' with types Bool, file: Nil, filemode: String, skip_request_body: Bool, skip_response_body: Bool, skip_benchmark: Bool, colorize: Bool
Overloads are:
 - Halite::Options#with_logging(format : String, **opts)
 - Halite::Options#with_logging(logging : Halite::Logging::Abstract)

This effected only in Crystal 0.28.
