problem getting dart_coveralls set up about dart-coveralls

[adracus]

I identified this issue in the git library which I am
using for dart-coveralls. I'll try to reproduce the bug and to fix it as soon as I can.

Awesome, thanks for taking a look. If you do find an issue in the git library please let Kevin know - it would be fantastic to get code coverage working for our dart projects.

Could you give it a try again? I tried to fix the issue in this commit.

[devoncarew]

Sure, I'll give it another shot.

Hmm, still an unhappy build:

https://travis-ci.org/dart-lang/usage/builds/44379782

Unhandled exception:
Uncaught Error: ProcessException: 
  Command: git show-ref HEAD --heads
Stack Trace:

(and it is using the latest version of the package - Activated dart_coveralls 0.0.17.)

I've now cloned the repository and am able to completely reproduce the bug. It seems happen because of the detatched head state through travis. I'll dig into this now and finally fix it.

[adracus]

I've fixed the detatched HEAD issue (now, if detatched HEAD state => try to get to the last branch). The issue should be resolved (again, hopefully this time), if I run the dart_coveralls report lokally in a dry-run it suceeds

[devoncarew]

OK, I'll give it another go.

Thanks, I have it working. I'm see some other issues; I'll close this out and file new items.
