tests: fix reference to undefined variable

The delaypush() function had a reference to "repo" that was clearly
supposed to be "pushop.repo". Instead of just fixing that, let's
extract "pushop.repo.ui" to a variable, since that's the only
piece of the repo that's needed in the function.

I have not looked into why I saw a different result in the test to
start with, but that's for another patch anyway.
