Import path is wrong in fire mortality functional test

[XiulinGao]

Describe the issue

blank_plot and get_color_palette should be imported from utils_plotting instead of utils, leading to test error.

fates/testing/functional_testing/fire/mortality/fire_mortality_test.py

Line 10 in f6355b1

from utils import blank_plot, get_color_palette
