[BUG] Sunlite Suite 2 - Batch mode delete of Init = Crash

[Superbaloo8]

Hello,

I found a bug with the function "Batch mode delete" which cause Sunlite crashing

Bug Scenario:
- Create a new empty show or not empty, doesn't affect the bug
- Try to delete the INIT scene with function Batch Mode Delete
- Validate the selection of Init scene - first alert ko
- Try to hide/show the master page = Crash of Sunlite

Bug reproduce with or without fixture page available.

If you validate twice the deletion of INIT, the first time you got the error message, second time, no error message, but bug still there
