"item.funcargs" is now filled during test execution time, not test execution
time.  I think it was never documented either way so i don't regard it as
an API promise.  Also, funcargs/fixtures are setup during test execution
so we can not generally make values available during collection.

With 2.5.2 you might still fish for the values, i think it's on 
'item.callspec.funcargs' or so but again, no promise.
