create_bar cannot handle >1 `num_stories_below_grade` when `story_multiplier_method` is `Basements Ground Mid Top`

[haneslinger]

to recreate, run and osw with num_stories_below_grade set to 2

heres an example stacktrace, on tag v0.7.1

this happens because this for loop excepts sorted_stories and stories_flat to be the same length, but this if else that populates stories_flat skips any basement story but the first to multiply the first.

@mdahlhausen If we can get this in for 3.11 it would be good. I hope maybe one line fix. I had not had chance to try to fix it yet. Can add new unit test with 2 or more below grade stories.
