Fix terminal panel not keeping up with dir changes
The terminal panel is supposed to show the same location as the currently active Dolphin view at all times.
However there was an issue when the terminal is supposed to quickly switch to a new location and then back again to the old one. The terminal ignored the switch to the old location unless it had already fully switched to the new location. Because it isn't particularly fast at fully switching to the new location, it would never do the expected thing of switching back to the old location.
This commit makes it so the switch to the old location is only ignored if there are no in-progress switches to a different location.
Not totally sure if this fixes everything but it seems like an improvement.
