crecord: fix blue artifact bug coming back from help screen
Before this patch, with record's curses interface:
- When one pressed the ? key to see the help menu and then leaves the help menu
- Then, blue artifacts would remain on the screen
This patch forces a screen clear / refresh after coming back from the help menu.
Since we don't have UI test for crecord I checked on my machine that the bug
does not reproduce.
