Fix two minor issues with the Java language module token extraction

[tsaglam]

This PR fixes three two issues with the token extraction:

1. Try and try-with-resource were extracted as different tokens
2. Try-catch-finally blocks did not correctly employ end tokens
3. Initialization and subsequent declaration of a variable in a single line vs. two line lead to different tokens

EDIT: Removed the last fix, as it affected the false positives enough while not affecting the true-positives significantly

This PR does not affect the E2E tests, as try/catch-blocks are not part of the dataset used there.
