To_hipscat fails with a catalog where columns has been added

As shown during the monthly hipscat working group meeting, the following sniper fails (last line, when uncommented), probably because of the problems in the metadata.

Hi @nevencaplar! I executed this snippet on both test data and ZTF (except for the loading of the 'm_ini' column) and I was not able to reproduce the issue saving the catalog with to_hipscat. @smcguire-cmu has access to the trilegal-flip catalog used here and, from what I could understand, this workflow worked as expected for him too. Do you have any idea of what the error was about?

It's because this code was executed with the map_partitions method defined in the image, which I think doesn't properly update the dask meta and causes issues from that. Our testing used the map_partitions that was recently added to LSDB in #290 that does update the meta. I think we can close this issue, that using the new map_partitionsin lsdb fixes things.
