Sorting on Balance Tab

[esengulov]

Sorting logic:

• default sorting should always be "by value", for coins that have balance.
• coins that have balance but no rate should appear after the coin with balance and rates
• finally should be coins that have 0 balance, sorted by market cap(if rates available)
• the sorting icon should appear after the user adds 5 coins.
• sort by options -- 24h volume -- name -- portfolio value -- market cap -- 24h change
