fix: remove unused attempt for account names counter

[janmichek]

Description

Initially I grabbed the issue #553
Found out that

1. Such an endpoint does not exist (requested here Add counter for account (active) names ae_mdw#1629)
2. There was a wrong attempt to get names count, that was not even implemented (dead code) SO at least I removed the dead code

Demo

Without any visual change. Should work the same

Checklist:

• I have read and followed the Contributing Guide
• remove attempt to get names count manually

As I understood the name counter isn't implemented yet on middleware's side. Besides that LGTM.

But I have a question: I noticed that on other pr name counter is working correctly and showing number of names. @janmichek Correct me if I'm wrong:

Good catch! There was a bug in app.
The count of names was taken from paginated response so it was always maximum of 10.

I removed that field for now, until we resolve it and will be able to show correct number.
Followup here #553

LGTM. AENS Names counter has been removed.

Makes sense, it was counting first page only.
