Do not modify Vagrant core object
Using [Array#keep_if](http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-keep_if) on a Vagrant core object can lead to unpredictable behaviour down the line as it modifies the object instead of creating a new one.
An example of such interference is described on https://github.com/cassianoleal/vagrant-butcher/issues/57. The problem with `keep_if` was identified by @sethvargo on this issue: https://github.com/mitchellh/vagrant/issues/5060#issuecomment-68107995
