Single Choice polls counting multiple votes

[aneeshjoshi]

This bot is awesome and just what we are looking for with regards to the anonymous setttings etc. However, just created a single choice poll on discord and on both the mac app as well as on my android device, if I tapped multiple choices prior to Pollmaster acknowledgement, the poll counted multiple choices.

Repro Steps:

• Create a single choice poll using pm!cmd or pm!advance
• set >= 2 options
• tap on multiple choices rapidly
• Then tap ? reaction

Observed Result:

• Multiple selections counted

Expected Result:

• Only the first (or last based on implementer's choice) vote that hits the db should be counted prior to the poll closure
