angular.uppercase is not a function on angular >= 1.5.0

[xirdneh]

angular.uppercase has been deprecated since v1.5.0 and now in v1.6.10 and v1.7 has been deleted.
According to this changelog: angular/angular.js@1daa4f2
angular.uppercase should not be used and instead use the internal toUpperCase.

If this is an acceptable change I can try and do a PR.

is there any update on this? I've got an urgent project failing that is hinging on this issue.
