Hide Switch button when only one account exist

Once we create a new wallet, we have Account 0 and Account 1 automatically created
(was it only to test the "Switch" button? Don't forget to fix it back before release)

Yeah, it was only to test path derivation and switch button out of the box, since there was no "create account" feature :)
It is fixed in #13

But probably I should also disable switch button in case there is only one account or add there an option "Create new account" 🤔

I would suggest hiding the button if only 1 account exists. The [create new account] option is in the settings and it's not something we need every day, so such a button might add unnecessary noise on this nice, minimalistic wallet screen. especially while using a smartphone

This button were "merged" with the account name in the new design.
It is still possible to click on it and see that there is the only one account, but I think it is fine to allow get used to the UI even if User does not have more accounts.
I'm closing this issue for now. But if you think we need to improve something — let's open another one and write a proposal.
