[Editor] Building for a platform using command line and not having that platform module installed will result in errors

Title: Building for a platform using command line and not having that platform module installed will result in errors: Building a player for 'Linux' (24) target is not supported in this Unity build.

Steps to Reproduce:
1. Create a blank unity project using any platform
2. Open up terminal and use Unity's command line parameters to build for a platform that you do not have the module installer for
3. Unity will open up, select a project to build
4. Observe the console will result in errors and the build will not build.

Expected Results: The message should state that the module is not installed not that the current Unity build cannot build that platform. Example: "Unity cannot build because the module for [platformNAME] is not installed"
