When saving My Account -> Default Settings, you are shown a stack trace

Steps to reproduce

1. Log in
2. Click on your username in the header, then My Account
3. Click on Default Settings
4. Change your Default Locale and click Save
5. You will see a stack trace like:

org.openmrs.ui.framework.UiFrameworkException: viewProvider adminui does not have a view named account/changeDefaults

Dev notes

I think the problem is an incorrect redirect after saving the data.

The fix is probably in this file: https://github.com/openmrs/openmrs-module-adminui/blob/master/omod/src/main/java/org/openmrs/module/adminui/page/controller/myaccount/ChangeDefaultsPageController.java
