Issues with code generation on Windows

[ia3andy]

Initially found by @stuartwdouglas:

• The zip does not unpack correctly on windows, instead of src/main/java/org/example/ClassFile.java you get src/main/java/_/org/example/_/ClassFile.java
• ${path} is not replaced with an actual value, so the generated application does not work

I am creating this issue in the launcher to keep track of the problem, but I guess it should be treated in https://github.com/quarkusio/quarkus since the project is generated using CreateProject: https://github.com/fabric8-launcher/launcher-quarkus/blob/master/src/main/kotlin/io/launcher/quarkus/LauncherQuarkus.kt#L45

This has been fixed
