This fixes an oversight from the move of nChainTx from the user-supplied snapshot metadata into the hardcoded assumeutxo chainparams. Since the nChainTx is now unused in the metadata, it should be removed in a future commit.

Thanks for the reviews @ryanofsky @Sjors. I've pushed a commit removing the nchaintx value from the snapshot metadata. This will of course render previously-generated snapshots unusable, but given that there's currently no way of actually making use of the snapshots I don't think that's an issue. |

Other than breaking half the CI's: sounds good :-) |
This value is no longer used and is instead specified statically in chainparams. This change means that previously generated snapshots will no longer be usable.
