Git Dependency fails to install when space exists in User Folder name #2015

Description

I have a user folder that has a space in it eg: C:\Users\Firstname Lastname
Git dependency resolution fails when attempting to clone from C:\Users\Firstname Lastname.paket\git\db\folder into the paket-files folder.

It correctly fetches the repository from a remote github based repo into C:\Users\Firstname Lastname.paket\git\db\folder

Repro steps

Please provide the steps required to reproduce the problem

1. Create a User with a Space in their User name, this will create a User folder that contains a space

2. Add git dependency in paket.dependencies

git git@github.com:MyOrganisation/MyRepo.git master build: "powershell build.ps1"

3. run packet.exe install

Expected behavior

Dependency should be installed in packet-files

Actual behavior

Paket failed with:
Checkout to C:\Working\MySolution\MyProject\paket-files\github.com\MyOrganisation\MyRepo failed.
Message: Could not run "git clone file:///C:\Users\Firstname Lastname.paket\git\db\MyRepo".
Error:
Cloning into 'Lastname.paket\git\db\MyRepo'...
fatal: 'C:/Users/Firstname' does not appear to be a git repository
fatal: Could not read from remote repository.
