"Fix" DoActionMove for war1gus:

war1gus' move animation is of the form
`{"unbreakable begin", "frame 5", "move N", "wait 2", "wait 1", "unbreakable begin", "frame 0", "wait 1"}`;
//                                           ^^^^ Computation here (unbreakable) :/              ^^^^^ and can be break here
(whereas wargus one is
`{"unbreakable begin", "frame 5", "move N1", "wait 2", "frame 4", "move N2",  "unbreakable begin", "frame 0", "wait 1"}`)
//                                                                                                             ^^^^^ computation here (breakable)
Computation on path (and IX/IY) was done on next (finished) `"wait X"` after reaching the tile (so was done **inside** the `unbreakable` section for war1gus).
Workaround is to do the computation only on new animation cycle.
Alternative:
- Grouping `"wait N1", "wait N2"` into `"wait N1+N2"` would not be enough (but would be fine).
- Compute path on first `"move"` is problematic (for Wait/unreachable).
