Fix compilation warning
chkViInputModeDefault seems to be redundant; looks like it was left behind during a code refactoring:
ktexteditor/src/vimode/config/configwidget.ui: Warning: Invalid signal/slot connection: "chkViInputModeDefault" -> "chkViCommandsOverride".
grep'ing for chkViInputModeDefault in the KTextEditor repo gives no results other than the one in the .ui file.
