Add methods for checking JTree node expansion/collapsing state in JTreeFixture and JTreeNodeFixture

It would be very helpful to be able to do something like this:

JTreeFixture fixture = new JTreeFixture(...);

fixture.requireCollapsed("Root/1/1.1/1.1.1");

fixture.requireExpanded("Root/1/1.1/1.1.2");

Same on JTreeNodeFixture:

JTreeNodeFixture fixture = new JTreeNodeFixture(...);

fixture.requireCollapsed();

fixture.requireExpanded();

Currently I have to go dig up the JTree instance, and do that way. I'd prefer

to use fixtures for this.

Start by reading JTreeFixture and JTreeNodeFixture alongside their existing fixture methods, then check the JTree expansion and collapsing APIs they wrap. The work is done when both fixtures expose the requested state checks for tree paths and current nodes, with tests covering expanded and collapsed cases.
