Improve address validation

[cryptoBeliever]

Current behavior

At this moment wallet is not performing full validation (with checksum check) for address on user input e.g:

• when putting the address on the transfer transaction form (simple and in aggregate)
• when adding to the address book
• when creating an invoice

Example invalid addresses:

• NCAPJJ712WUYFFTBCPY3CZUEFJYVQUHQ5DH5HAA
• NCAPJJ712WUYFFTBCPY3CZUEFJYVQUHQ5DH5AAA
• NCAPJJ712WUYFFTBCPY3CZUEFJYVQUHQ5DHAAAA

What's the issue?

Because of limited validation, there are often problems on the serialization level where the wallet is unable to create transactions.
For example when I'm using an invalid address (TCAPJJ712WUYFFTBCPY3CZUEFJYVQUHQ5DH5HAA) and trying to send tx serialization failing:

Expected behavior

The wallet should validate provided by the user's address strictly with checksum checks.
