Weariness indicator is useless for actions that take >1 turn

# Describe the bug

Sidebar weariness indicator, which is supposed to show info about weariness, is showing it regarding your current status instead of last action you take. For actions taking less than a (or maybe exactly one) turn, it is correctly showing activity level, weariness malus and so on. For actions that take more, it is showing `none` AL, and +0% malus.

# Steps To Reproduce

1. Make a player with slow 2h weapon
2. Achieve at least 1st tier of weariness
3. Try fighting zombies, see activity level staying at none but time flying by

It is actually flicking through 'extreme' but good luck noticing it if you don't know WTF is happening. See here https://www.twitch.tv/videos/1056295433 from about 2:28:30.

# Expected behavior

It should show AL of *character's last action* instead of showing... whatever it is. I guess because you've spent too many points previously, you arrive to current turn without technically performing an action at the beginning of it, so it counts as no activity? Or something?

Start with the sidebar weariness indicator while reproducing the issue using a slow 2h weapon and a character at the first weariness tier. Trace how the indicator handles actions lasting more than one turn, then verify that fighting zombies displays the character's last action activity level and weariness malus rather than none and +0%.
