do not remove try block if there are resources

[joanvr]

What's changed?

Try with resources can have side effects (closing the streams) even with empty try blocks. So we cannot delete it safely.

Modified the emptyTry test to not have resources (so it's removed because it's empty), and added a new emptyTryWithResources that is actually not removed because it has resources.

Anyone you would like to review specifically?
