Relic Mod Description Crash Handler

`Relic` mod with combination of some other mods causes this crash sometimes
```
java.lang.NullPointerException: Cannot read field "f_40220_" because "entry" is null at it.hurts.sskirillss.relics.client.handlers.DescriptionHandler.onPlayerTick:L70 at it.hurts.sskirillss.relics.client.handlers.__DescriptionHandler_onPlayerTick_PlayerTickEvent.invoke:dynamic
```

So this mod is intented to prevent those crashes while writing necessary information into the log file so I would be to research what's the core issue later on.
