NullPointerException in CourseColor.getColor() when using plugin

[Kirrr1999]

Description:
When using the plugin to open new exercise in Pycharm the options do not load and you get an pop up , an internal IDE error occurs due to a NullPointerException in the CourseColor.getColor() method. This seems to be caused by a missing null-check.

Steps to Reproduce:

Open IntelliJ with the Dodona plugin installed.

Attempt to open the exercise identification dialog.

Observe IDE error popup.

Expected behavior:
The plugin should handle null CourseColor values gracefully without throwing an exception.

Stack Trace:

Thanks @Kirrr1999 for notifying us of this issue, with full stack trace information!

This issue should now be resolved in the latest version of the plugin.
