Expected behavior

The Account.get_voting_power() method should return a float type variable representing the accounts current voting power. The methods comment is as follows:

Returns the account voting power in the range of 0-100%

Actual behavior

The error below is encountered when pointing to nodes on Hard Fork 20 ('0.20.2')

Traceback (most recent call last):
File "", line 1, in 
File "/usr/local/lib/python3.6/site-packages/beem/account.py", line 347, in get_voting_power
total_vp = (self["voting_power"] / 100 + regenerated_vp)

return super(BlockchainObject, self).getitem(key)
KeyError: 'voting_power'

It has come to my attention while troubleshooting issues with the @steemflagrewards bot that the get_voting_power() method does not appear to be functioning on HF20 RPC nodes. If you connect to https://api.steemit.com or https://rpc.buildteam.io, you may have noticed the error when you call the method.

Notice what happens when I connect to @gtg's node which is not on HF 20.

Conclusion

As there are so many Steem blockchain application dependencies on Beem, if all RPC nodes are upgraded to HF 20, there will be a significant impact on any tools that leverage the get_voting_power() method. @steemflagrewards upvote queue functionality and thus our abuse fighting capability would be in a degraded state until a workaround is identified. For the time being, we are ok while @gtg's node is still on HF19 and we will work on finding another for redundancy.

I have notified @holger80 via DM and informed the Steem Devs discord and the Beem Discord of said issue. Thank you!
