LibGUI: Don't re-trigger the autocomplete box when the timer fires

Browse Source 
Previously there was a situation where the autocomplete box would
appear to "jump" to the side. This was due to the following race
condition:

1. Start typing, thus triggering the autocomplete timer to start
2. Manually trigger autocomplete before the timer finishes
3. Continue typing
4. The autocomplete timer now fires

When the timer fires it causes the autocomplete box to show, which, if
it is already shown, has the effect of moving the box to the current
cursor position.
