Log flooding bug if 'current universe' is not found (eg, no headset)

[Spazznyan]

Running SlimeVR server and SteamVR (with slimevr driver enabled) while no headset is connected results in a very quickly growing Steam\logs\vrserver.txt log being rapidly spammed with "slimevr: Failed to find current universe!" at the rate of about 500KB per minute

I tested with server versions 0.9, 0.11, and 12.1. All versions present the same behaviour.

Ah. That's being logged here:

SlimeVR-OpenVR-Driver/src/VRDriver.cpp

Line 122 in 3aa3792

Log("Failed to find current universe!");

That should probably be replaced with something that only logs once to avoid the spam.
