Fix for commit component with empty args object

[bakkerthehacker]

Flatten total-lines-changed object to allow the commit object to not error when passed an empty object.

Under which circumstances an empty object would be passed in? How can I reproduce this?

[bakkerthehacker]

I have had this issue occur a few times on a repo. Not sure if theres something weird going on that repo or if my diff tools are interfering with ungit, but I have gotten crashes in commit.js with total being undefined.

I am unable to determine exactly what causes this or how to reproduce it.

Thanks for fixing this, I did manage to get it to happen again:

Which version of ungit do you use?
Can you inspect the network trace for /gitlog requests and paste the json here?
Or you can try logging it here manually via console.log:

ungit/source/git-promise.js

Line 449 in 51bd6d9

log = log ? log : [];
