jbang init gives no error and generates no file when using existing file as part of name

[maxandersen]

discovered this using jbang idea that has a bug and create this kind of jbang init:

 jbang --verbose init --template agent someexistingfile.java/wonka.java

This result in printing that someexistingfile.java/wonka.java is created - when it most definitely was not ;)

expect to error saying that it can not create such file

The error could be fixed by:

1. First converting the file path to an absolute path using "new File(filepath).getAbsolutePath()".
2. Check that each dirname in the absolute path is a directory (if it exists) and not a file
