This looks like a breaking change so it should wait for Material 1.2.0.

@mgol This just changes the test-versions.sh file which is used for testing on the above linked Jenkins. There is one test that is already failing on AngularJS 1.4 and the change for that is part of AngularJS Material 1.1.6 (needed by a Googler). This change doesn't actually change the bower-material package.json to drop support for AngularJS 1.4.

Also note that we don't test 1.4 on TravisCI anymore either (this was changed long ago).
