@rarkins Should we throw error for all instances where we execute git commands these changes suffice?

[rarkins]

If you're going to wrap in a catch then you need to throw again after

[rarkins]

Instead of so much error handling I think let's just add a git status command after clone and hope that it is enough to trigger the error early.

We should keep the check on isBranchModified incase execution fails to stop during cloning. For any branch that exists & has cache that's the first call which clones the branch.
