terraform version check fails for TF 0.13.5

[solitaryr]

We're moving to TF 0.13.5 from 0.12.23 and our circleci jobs are failing on the version check step with the following error

rm -rf .terraform
terraform init -input=false -backend=false -no-color "$module_path"
terraform version -input=false -no-color

Reading required terraform version .tfswitchrc

Usage: terraform version [options]

-json Output the version information as a JSON object.
