Missing null check in TileEntity.getCapability() casuing NPE with some other mods

@Override
public <T> LazyOptional<T> getCapability(Capability<T> cap, Direction face) {
if (!this.remove && cap == ForgeCapabilities.ITEM_HANDLER) {
if (this.getInventoryIndexForFace(face).isPresent()) {
return this.itemHandlerOpts.get(this.getInventoryIndexForFace(face).getAsInt()).cast();
} else {
return LazyOptional.empty();
}
} else {
return super.getCapability(cap, face);
}
}

Here the 2nd parameter (face) is nullable, causing an NPE in the getInventoryIndexForFace() method when used with other mods.

Here's one example of the crash with the MultiStorage mod (I only kept the useful part of the log):

java.lang.NullPointerException: Cannot invoke "net.minecraft.core.Direction.ordinal()" because "face" is null
