pw_console: Bugfix for disabling follow mode
pw_console: Bugfix for disabling follow mode

The log window render function was re-enabling follow mode
unnecessarily. Pressing a key or clicking the mouse triggers this
function call. So if the user presses 'f' to disable follow, it got
disabled but immediatley re-enabled when the UI was re-rendered.
