Updates the metadata object stored about the user by doing a shallow merge of the stored and the update JSONs
and removing properties set to null on the root level of the update object. The merged object is then reserialized and stored.

e.g.:
  - stored: `{ "preferences": { "theme":"dark" }, "notifications": { "email": true }, "todos": ["example"] }`

  - update: `{ "notifications": { "sms": true }, "todos": null }`

  - result: `{ "preferences": { "theme":"dark" }, "notifications": { "sms": true } }`
