add --profile=black to isort args

[LukeWood]

This causes isort to respect the rules of black. Without this,
if you have any long paths isort will wrap them as follows:

from my_long_path_import_something.something import
Symbol

while black does:

from my_long_path_import_something.something import (
Symbol
)
