Plugins and themes deleted when fetch button was pressed

This was happens in my server Centos7 in the Google Cloud Platform.
Initially the plugin printed the message of error in execution of the file ssh-inc.
I deactivate the selinux temporably with setenforce 0 and clicked in the "Fetch repository".
In this moment, majority of the plugins and themes was deleted.

I see in the file inc/class-git-wrapper.php:644 have rm -rf.
I suggest to change it, it is too dangerous.
