Unicode Decode Error in "Get Current Agents" REST API Call

Empire Version

2.3

OS Information (Linux flavor, Python version)

Tried under macOS and Kali Linux

Expected behavior and description of the error, including any actions taken immediately prior to the error. The more detail the better.

I got two active agents on Empire. Information regarding to these agents are listed below:

When I execute "Get Current Agents" API call, I got following error:

UnicodeDecodeError('utf8', 'n\x91I/g\x05J\xfc\xdd\x01\xf1\xee>A\\\xeb\xe0\xe1\xee\xb9\xf537}\xa7\xb2\xfaK\xd2\x05\xc0Y', 1, 2, 'inval
id start byte')

I believe the problem is related with second agent's session_key. There are some characters shown as "?". Also, when I remove this agent and make the api call again, it works without a problem.

@utkusen thanks for pointing this out.

@xorrior for your information I fixed this by changing "session_key":session_key to "session_key":session_key.decode('latin-1').encode("utf-8") on empire file line 743 (https://github.com/EmpireProject/Empire/blob/master/empire#L743)

@utkusen would you mind submitting a PR for the fix you implemented?
