fix(gui): The result in usage search should sort by name

[cyqw]

The result in usage search is sort by CodeNode::COMPARATOR, it's not suitable for human reading.

@cyqw I see what kind of issues you are trying to fix, but it is better just to fix that comparator. And only name is not enough here because, for example, variable usage needs to be sorted by usage place not name (check #1104).
So, I suggest fixing CodeNode comparator to sort by long name which used in first column renderer (here) to:

	private static final Comparator<CodeNode> COMPARATOR = Comparator
			.comparing(CodeNode::makeLongString)
			.thenComparingInt(CodeNode::getPos);

Please try to apply this change and check if it fixed your issue. If still not, share a screenshot of case which you want to improve.
