Can not run multiple pacu sessions

[snowmirage]

I just spent a good few hours chasing strange errors running modules against 2 different AWS accounts. Only to find some very unexpected behavior in pacu.

To reproduce

Open 2 terminals

In terminal 1 run pacu and create a new session named "SESSION1"

In terminal 2 run pacu and create a new session named "SESSION2"

go back to terminal one and hit return and it now says SESSION2 in terminal 1.
