collapse: getting target via .attr instead of .prop

commit 3f017db297c4 has broken standard collapse/expand diff feature:
for some unknown reason, the target attribute cannot be retreived like this
with the .prop jquery function, so reverting it back to something that was
working (.attr). Apparently the original change was untested ;-)
