Provide better feedback for addresses with no activity yet
We should provide better feedback to a users when searching for a valid address with no activity yet. Instead of showing, principal not found, we should change this to something like: no activity has been found. Also, should we show something different on these address pages? @jasperjansz any thoughts?

To repro:
- Search for a valid address with no activity yet
This is a good idea, though I'm curious about the immediate context here.
Did this come up for a user who had an address on hand from the wallet without any activity yet, but looked for that address in the explorer for some reason?
It's mostly just the copy that is confusing. If it's a valid address, it's not accurate to say its not found.
@jasperjansz says we should take the user to an empty page instead of showing any error here within the search autocomplete. That gives the more accurate impression that the address "exists" but has no activity yet.
Yeah, as a user I might want to verify that my STX address was written right but that its a mainnet address that exists. Taking folks to a page that simply shows that address with no activity would be great.
After looking into this problem, we couldn't find a solution for empty accounts
