Fix #69
Tested in my vagrant environment.

Before

vagrant@st2vagrant:~$ sudo st2 trigger list --pack=napalm

|                           |        | decrease                  |
+---------------------------+--------+---------------------------+

Hi @taijiji . Looks good to me. I suspect this trigger name went undetected as the example rule that references the LLDP sensor trigger only references LLDPNeighborDecrease (probably enough for the original demo) .. see here. The sensor itself would actually emit an LLDPNeighborIncrease trigger on LLDP neighbor increase and your change will ensure that trigger is registered with stackstorm.

Thank you for contributing!
