Better error handling - panic instead of "failing up"

If the gotestsum isn't installed or your $GOPATH isn't in your $PATH, you'll fail to call gotestsum after querying your model.

Here is an example output. The part that's actually relevant is marked as bold and it's kind of in the middle of the other "spam" that's not really relevant.

Another standard error close to this position was, that my generated program tried to include libs that I don't have installed.

The tests should produce 100 percent code coverage and must compile. The response must contain only the raw test code and nothing else.
    ```golang
    package plain

    func plain() {

Calling with a symflower model when you don't have the symflower stuff installed also doesn't fail very gracefully.
