Decouple aens claim and preclaim transactions

[CedrikNikita]

This PR includes several improvements:

• fixes Bug registering name #661;
• fixes de-couple NamePreclaimTx and NameClaimTx in AENS claiming process #2200;
• fixes Improve text on modals (nonce error) #2645;
• user will no longer be able to preclaim exact the same name, while claiming name is in process (this currently results in infinite loading)
• an account that claims a name will no longer be blocked from usage during claiming process. It took up to ~5 minutes. (all other transactions while the name was in the claiming process were accumulated in a pending state and were not executed until the name was claimed);
• fixes an issue that caused the pointer to not be set to the current account if the user navigated off the page, closed the extension, and so on;
• allows to claim several names one by one without any problems;
• pending name now appears instantly, claimed name will also appear instantly in the wallet;
• reduces the number of name check requests;
