Use GitArgumentBuilder to generate git commands in all git calls

[vbjay]

Do you want to request a feature or report a bug?
Bug
What is the current behavior?
We have calls to git not using the GitArgumentBuilder which means it can't provide the fixes that class was designed to do.
If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
Some cmd calls will fail if the right configurations are not set.
What is the expected behavior?
All RunGitCmd calls and other ways of running git commands use GitArgumentBuilder
Environment you encounter the issue:

• GitExtensions version:Master
• GIT version: NA
• OS version: NA
• .NET version: NA

Did this work in previous version of GitExtensions (which)?
No
