fix(identitygrouping): delete obsolete "hash" field from IdentityGrouping

djcsdy · djcsdy · commit 9ae11c39545c · 2021-04-19T22:52:12.000+01:00
This is no longer used. The value itself can be used as a hash via ES6 Sets.

BREAKING CHANGE: IdentityGrouping no longer has a "hash" field as using a hash no longer provides
any benefit.
