Fill the domain field in Commands window

[badlop]

This is a minor suggestion for a small improvement.

Is your feature request related to a problem? Please describe.

This is the current behaviour:

1. Click on the Settings icon
2. Click on Services
3. Converse shows a field already filled with the current domain, and its results
4. Of course, the user can enter a different domain in the field and click the button
5. Now click on Commands
6. Converse shows an empty field for the user to enter some domain or JID

Describe the solution you'd like

It would be great if Converse fills the field in step 6 with the server domain, just like it already does with the field in step 3.

Describe alternatives you've considered

Right now, for my personal usage in my local test server, I simply force "localhost" like this:
