Fix Lifx local IP repair not being applied

- The previous LIFX fix (1eeaa26) was not being applied as the function to get the local IP was caching the previous value. The caching has been modified to account for the empty source scenario.

- Added an `info` plugin message to Lifx to help debug this issue.
