Allow initialization of cobra project from within a go workspace/monorepo. resolves spf13/cobra-cli#26

Resolves spf13/cobra-cli#26

Running cobra-cli init... in a module that is part of a go workspace fails because of a JSON parsing error. The error is the result of expecting a single object from the command go list -json -m but receiving multiple objects - one for each of the modules in the workspace.

By setting the environment variable GOWORK=off before running cobra-cli, the go list -json -m command reverts back to returning the single object cobra-cli expects.

An alternative solution would be to parse the output of the go list -json -m command with a json.Decoder rather than json.Unmarshal and match the module directory to the correct object decoded. The environment variable solution implemented here seemed cleaner to implement - however should cobra-cli require further interaction with workspaces going forward, using json.Decoder may be a more appropriate approach, at which point this environment variable must be removed.

No new tests were created for this fix as none of the existing tests pass as is.
