`ivy-resume` does not display `counsel-git-log` output correctly

[leungbk]

After using counsel-git-log and getting some results, attempting to ivy-resume causes the results to be displayed line by line. This seems to be because ivy-resume does not set counsel-async-split-string-re to the desired \ncommit as counsel-git-log does.

Should counsel-async-ignore-re and counsel-async-split-string-re be made into alists keyed by async counsel- commands?

Thanks, please test.
