Fix removal of duplicate repo on Windows

[christophebedard]

Fixes #578

This makes sure that the paths returned by vcs are valid POSIX paths so that rm -rf works.

I tried for hours to use sed directly in the execBashCommand() call, but it never worked. It feels like something somewhere is messing up with the escape characters (it worked fine on Ubuntu).
