bug; ui, Bulk deleting templates presents user with 404 screen after closing window.

[ianc769]

problem

When using the bulk delete templates option, I am presented with a generic 404 screen after the deletion completes and press close on the Bulk Deletion window.

versions

Cloudstack 4.22

The steps to reproduce the bug

1. On the templates select a template
2. Click Zones
3. Add a check to every zone
4. Press bulk delete templates
5. Press close when completed.

What to do about it?

This should probably redirect the user to the templates page, instead of showing 404 on the now deleted template.
