Fix #3334

Hi!

This is a suggested fix for #3334. To the best of my knowledge, this does the same thing that @Egor18 implemented with #3331, but using the JDT tree instead.

Please see #3334 for a detailed description of the problem. I'm also running some tests locally with Spork to see if this solves the problems I encountered, will check back once those have completed.

This fix caused further issues for me. Will keep debugging. It may be a problem on my end and not in this fix itself.

After a lot of testing, I've found that the further issues I encountered were caused by Spoon incorrectly marking some package references as implicit (that are in fact explicit), and vice versa. I'm currently trying to figure out whether the two problems are related or not.

EDIT: Seem unrelated, see this issue: #3336

Thanks a lot, merging this one which is atomic, CI green and LGTM.

#3331 introduced a major regression see https://ci.inria.fr/sos/

Let's how this better fix improve the situation.
