dynamic model via directive doesn't work properly

[mih-kopylov]

There're several bugs:

• when dynamicModelAttribute is set, it adds $watch for evaluated $scope.$eval(attributes.dragularModel) and in apply function there's second evaluation: drake.sanitizeContainersModel( $scope.$eval( newVal ) ). Obviously when I have expression dragular-model="data.model", it's evaluated to array in $watch, and then it tries to evaluate the array again.
• the result of the evaluation is set to drake.containersModel, but this property of drake isn't used in dragularService, private variable o - shortland for options is used instead

Should be working correctly now, please update to v4.4.2 and let me know, thank you for your contribution 👍
