insert skeletons migration: fix for non-local locals

Closes #1746

See merge request pleroma/pleroma!2502

Apparently some instances have local users with local ap_ids
that are marked as local: false. Needs more investigation into how
that happened.

In the meantime, the skeleton migration was patched to just ignore
all known ap ids, not just locals. Doesn't seem to slow down the migration
too much on patch.cx
