[REFACTOR] Refactor the AGit code
TLDR: Less code, better maintainability and more comments. - Add code comments to explain what the code does, it's quite a big function so it definitely deserved some of that. - Simplify some logic. - Load the `pusher` in a single place. - Update the error messages to be more correct, not capitlized, include more debug info and remove 'Error:' As it's no need to indicate that, errors are concenated with `:` seperators. - Improve the message that a change was rejected, because a force push was detected and the `force-push` option wasn't set. - Avoid a second time loading `gitRepo.GetObjectFormat` and handle the error gracefully for the other occurence. - Adds integration test for force push detection.
