Fix EntityComponent handle entities without a name

[balloob]

Description:

In #7681 we added ordering to groups created by the EntityComponent. That PR incorrectly assumed that all entities always return a name.

To keep consistent ordering, entities have been converted to an ordered dictionary.

My bad. I actually did check that assumption but I may have mixed up name and entity_id during my investigation :-(

Anyway, this PR re-introduces the issue #6557 that I tried to fix. The point is to have group.all_scripts and group.all_automations sorted alphabetically for the UI.

I actually do not think the OrderedDict even makes a difference because it seems that entries are added in an arbitrary order during startup(?). So every restart we get a new order anyway.

I propose to instead make the sorting work for None names, maybe like this:

	ids = sorted(self.entities, key=lambda x: self.entities[x].name or x)

Scripts are based off the configuration, which is parsed into an ordered dict by YAML. So if you want to re-order it, just change the order of the scripts.

That's not what I observed. Unfortunately, I will not have time to test again today.

Getting the lists stable between restarts would be an improvement but I do think alphabetical is a better default ordering and it is also how the default factory view presents things (last I looked, anyway).

You're right for non-scripts, like platforms. As discovery can always change. I'll pick your solution 👍
