[JavaHL] SVNClient.info2() fails when used with revision or peg revision

Hyrum, SVNClient.info2() is failing to retrieve the full information
for a Java Info2 object when used in conjunction with a revision or
peg revision. The third call to info2() in BasicTests.testBasicInfo2()
will trigger this problem. Try it with the following patch, and
you'll see what I mean:

Index: InfoCallback.cpp

     if (!entry)
     {
         // We want to store a NULL in the resulting array, but we can't put a

entry=0x0
entry=0x0
entry=0x0
...

I'm going to commit the refactoring I was doing when I discovered this
problem, and make this part of the test XFAIL.

On a related note, the first time the callback is invoked, it's
building a path like ".../test-work/working_copies/basic_test3/basic_test3",
apparently due to SVNClient::info()'s invocation of InfoCallback::setWcPath().
