Add "Create new key" option to key selection drop down in Create/Edit Account popup

As in the rec. Creating a new account will create a new record on the list, but it will be the same exact account. It's not only a displaying issue, the exported account files are also exactly the same. (as discussed - the reason behind it is that the account creation does not automatically create a new key for the account, it uses the existing key)

I noticed the same while testing the deleting keys/accounts.
Delete Key- create a new key pair, you will get the exact same key over and over again.
I thought that it could be the cache issue? To be checked, I could easily reproduce it

It's not a bug. You are using the same key, and that's why you get the same address.

However, we may need to tweak GUI and show a messages like:

• You already have such an account with the name "XXX"
• or Some of your accounts already using this key (in case it is used in different account, but not the same as you're trying to create)

As we discussed on the call, I'll add "Create a new key" option to the dropdown and make it default (for SingleSig for sure).
Also I think that showing a message is still actual. So I'll add it as well.
Then I think it will be enough UX tweaks to not have confusion anymore. :)
