[Bugfix#2094] Fix handling of balances when user has no tokens.

[jfarid27]

Description

Adds handling of user data when there is no tokens but ETH in the account.

Fixes #2094

Before

After

Motivation

Attempted to check an address of mine that only has ETH. Because of the token empty default line, it fails a number conversion in decimals and breaks.

Dependencies

None

How has this been tested?

• Manual testing was done on my own address. The current tests require a mock to be added with this edge case state. Added unit test and cassete in ethplorer_model.
