Duplicate menuCell items

Bug Report

Duplicate menuCell items appear randomly in the menu when trying to present the same cells, it might be the previous cells are not getting deleted?

Tested with the iOS Smoke Tester app(sdl_smoketester_ios) /branch develop:

1. Open the app on Manticore
2. Click on Screen Manager - Main Menu -> Menu Forward on the device cell to upload a menu
3. Wait for menu to be uploaded, then click on Screen Manager - Main Menu -> Menu Reverse cell to upload the reversed menu
4. Before the menu in step 2 gets successfully uploaded, click Screen Manager - Main Menu -> Menu Forward
5. Repeat the fourth step immediately after

Might need to repeat the steps above few times before you can see the bug

Use the following scenario mainMenu = [menuA, menuB, menuC; menuA.subCells = [subcell0...subcell49]
mainMenu = [menuC, menuB, menuA]
