[MC-119000] Fire charges no longer immediately detonate minecart TNT since 1.12-pre6

The bug

Prior to 1.12 burning arrows or fire charges hitting a TNT minecart would cause it to immediately blow up however in 1.12 burning arrows continue to immediately destroy minecart TNT but fire charges only ignite the TNT in the minecart.

Side note

This behavior changed as of 1.12-pre6, at the same time MC-116669 was solved.

Code analysis

Based on 1.12 decompiled using MCP 9.40 PRE 1

The method net.minecraft.entity.item.EntityMinecartTNT.attackEntityFrom(DamageSource, float) now only explodes the minecart directly if it was damaged by a burning arrow. In all other situations it is only ignited.
