AB#340 Fix travel companion repeating card

[sharhio]

Proposed Changes

• getting the legs of interest now uses the actual current time to ensure the legs are always relevant and that there is no time jumps back and forth in the time that is supposed to be current.
• getLegType now uses the actual current time to check if the journey has started (affects the glitchy card showing up briefly)
• The nextLeg is also reverted to the previous value when the animation is in motion to keep the view consistent.
• legChange value is taken into account when determining whether to show previous or current leg info to ensure that there is no rendering glitch while the cardChanging variable with timer is being set.
