Fixed my own issue, #1524

As outlined in GameServerManagers/LinuxGSM#1524, the PushBullet alert
script was somehow printing the same text twice in a single field. By
removing the reply variable from both the fn_rawurlencode() function and
from the variables used not 3 lines down, we produce the intended alert.
