'migrate' removes line break(s) at the end of a file

[Frank Weigel]

While working on SAP/openui5@c782ce9 , I encountered the following issue with the ui5-migration tooling:

In files that are not touched otherwise, line feeds at the end are removed. While this doesn'T cause build or runtime issues, it creates a lot of noise in changes and the only workaround seems to be to revert those changes manually, which is cumbersome.

To reproduce, you can execute the following commands

cd openui5
git checkout 6555a38
ui5-migration migrate src/sap.ui.core/src/sap/ui/dom/jquery

simplified example using replaceGlobals task

before 8 lines:

sap.ui.define(['sap/ui/thirdparty/jquery'], function(jQuery) {
	"use strict";

	return jQuery("a");

});

after 6 lines:

sap.ui.define(['sap/ui/thirdparty/jquery'], function(jQuery) {
	"use strict";

	return jQuery("a");

});
