## Description of the bug
Go invis as lurker slash sentry, remain invis.

## What's the difference with what should have happened?
I'd expect the lurker to be revealed considering slashing a marine causes them to be revealed.

## How do we reproduce this bug?
1. Go lurker
2. Go invis
3. Slash inanimate object like sentry.
