[BUG] Quirk in saving webclient layout

[Griatch]

Describe the bug

It's visibly possible to circumvent the block against saving the default webclient layout. It doesn't actually work, but it's confusing.

To Reproduce

In webclient, open options:

1. Start to edit the default layout name by adding more letters to its name, like default1234232
2. The Close Options and Save button becomes active
3. Without saving, erase the extra letters, down to default
4. The Close Options and Save buttons remains active and you can now save your modified layout as 'default'

The save does not actually happen (so this is correct), as loading default returns the 'real' default layout.

Expected behavior

The default button should remain greyed out whenever it's about to save something named default. While the above behavior is apparently benign in the sense that the default layout is not actually saved, it nevertheless confuses the user.

Environment, Evennia version, OS etc

Evennia master branch.

#3282 is merged and closes this issue I believe. Currently unable to reproduce. @Griatch
