Ergo worker names are not displayed correctly in miningcore 
I've noticed strange behavior in Miningcore with workers: depending on your mining client, they will not show on miningcore CLI/Logs, however, I can confirm T-REX on windows (with the -w flag) does show up - but only on the logs.

when looking at the API under _/api/pools/POOL_NAME/miners/ERGO_WALLET_ADDRESS/performance_ no worker names are displayed.

I have tested Lolminer 1.52+ on Linux and T-rex 0.26.14 on windows.

(sorry I did not include "performance" in original issue. I believe I have described it properly now, and you can see no workers are shown in the above screenshot)
