Handle corrupt git clones

Browse Source 
When cloning the git repo:
1. Try to clone
2. If there's already a build directory reset it
3. Check the clone is valid

If anything goes wrong during that process:
1. Delete the clone directory
2. Clone it again
3. Check the clone is valid

Raise any errors after that
