Check for an Xcode installation before installing the CLI tools.
Check for an Xcode installation before installing the CLI tools.

In some cases, users will already have Xcode installed but not all of the required dependencies (like Node), but xcode-select throws an error if Xcode is already installed.

This change will check for an existing path before trying to install the tools.
