fix: set empty names as shortened address

[iamacook]

What it solves

Resolves #3526

How this PR fixes it

If an empty name makes it's way to the address book reducer (be it by adding or importing), it is set to a shortened version of the given address.

A temporary dispatch sets any existing empty-named address book entries to be the same as the above.

How to test it

Remove the name name of a contact in the locally stored address book. Refresh/navigate to the address book and observe the shortened address be in place of the name.

Nice idea using short addresses! I would go for 4 symbols, not 8, though.

Looks good to me.
The name is fine, it shows also the same in the owners' list. The name still works like any other name, it can be edited just fine, is used if another safe is created with that user as owner...
