Ensure that at least 4 letters of token symbol are shown in "Portfolio" section on wallet dashboard

Wallet version or commit SHA: 71bee7e

Environment: Win 10 Home (64 bit) Version 1709 Build 16299.371

Prerequisites: At least one wallet imported to the app, Balance of token which has at least 4 letters in token symbol

Reproduction steps:

1. Start Neon Wallet
2. Click on “Login using a saved wallet” button
3. Select your wallet, enter your passphrase and click on “Login” button

Currently, if token symbol contains more than 3 letters, it’s getting trimmed after second letter. Taking THOR token as an example, we’re ending in TH... token in “Portfolio” section. This could cause issues in future in understanding current balances of wallet and confusion. Adding another token, for example THEST, user will see two tokens in “Portfolio” section named exactly the same - TH.... Because the most common cases for token symbols are 3 and 4 letters, we should ensure that at least 4 letters are shown. In addition to that, if token symbol is trimmed anyway (because it’s longer than 4 letters), tooltip on mouse hover should be added showing full token symbol inside (it’s not present currently).

@drptbl I fixed this. It’s currently pending QA. @Melicio I checked the string “ATLAS” on the panel and it looks like you’re all set! 👍 :shipit:
