SourceTree should trust internal CA that are available at the OS level

link with SRCTREEWIN-1858

my local system git is configured to OS approved certificate with the configuration commande

 git config --global http.sslBackend schannel

SourceTree won't work with, instead of the "terminal" commande line launch from sourceTree

I must have admin right to force git configuration

 git config --system http.sslBackend schannel
