### Describe the issue

bitcoin-qt: Debug pop-up window, Peers tab, right-click ban node for 1 hour, day, week, year does nothing. Disconnect node still works.
### Is the issue reproducible?

Yes.
#### List steps to reproduce below:
1. build master branch after commit https://github.com/bitcoin/bitcoin/commit/6423116741de2144872389cf63a621539ae79aaa
2. launch bitcoin-qt (on testnet is advisable)
3. test ban node list right-click functionality on Menu->Help->Debug pop-up window, Peers tab.
