Remove "extraBundledJars" task, which nothing else actually uses

Some tests in other subprojects do depend on some these extra jar
files.  But they can declare those specific dependencies as needed.
Nothing seems to depend on the entire group of extra jars, so it's not
really useful to declare a task that is merely an alias for all of
them.
