Fix exposing fields for SyncDelegates (#437)

Currently, exposing fields expects the method to provide a full path to the fields, instead of a field relative to the parent object.

For example, before this change the paths needed to be:
`RimWorld.SocialCardUtility+<>c__DisplayClass42_1/roleChangeRitual`, `RimWorld.SocialCardUtility+<>c__DisplayClass42_1/ritualTarget`, `RimWorld.SocialCardUtility+<>c__DisplayClass42_1/CS$<>8__locals1/pawn`

After this change, the paths now need to be:
`roleChangeRitual`, `ritualTarget`, `CS$<>8__locals1/pawn`
