infopane: HandleEvent: reset key sequence when handling y/n prompt

Fix the following buggy behavior:

1. bind "<n><a>" to the Paste action in the command bar
2. open a split pane, type some text and press Ctrl-q to close it
3. answer "n" to the "Save changes before closing?" prompt
4. press Ctrl-e to open the command prompt and press "a"

-> result: instead of inserting the "a" letter, clipboard is pasted.
