[CLIENT] Master Page Name Bug

The bug is located on the mastery page editor in the user's profile, in client. When the client is editing their masteries and attempts to save or move to a new mastery page, the client will pull up a window saying "Unexpected Platform Error". This only occurs when the user attempts to name two pages that are identical (case insensitive) and appeared as I was making a new Support page. Changing the name of either page will stop the error message from continuing to pop up.

1. Open mastery page and save a page with any name (in my case support)
2. Open second mastery page and save that one with the same name (for example Support), note that the name is not case sensitive.
3. Watch the error screen pop up.
4. To stop the error screen, rename either page.
