MDL-42928 Filepicker: Disable behat tests run by phantom

There seems to be a bug relating to overflow: hidden on the body tag in
some cases which is only showing for dialogues which belong to the
filepicker.

Disabling these for the moment as this issue may be related to MDL-43712
which is a work in progress.
Merge branch 'install_master' of git://git.moodle.org/moodle-install
weekly release 2.7dev
