Iam/remove iam caching

[rgomezp]

Description

One Line Summary

Removes IAM caching (follow up on #1486).

Details

We should not cache IAMs since it is incongruent with RYW consistency.

Example: there is an IAM targeting users on version 1.0. The user upgrades to 2.0 & should no longer see the IAM targeting 1.0.

The source of truth is the backend & we should only show IAMs as calculated by segment membership.

Testing

Manual testing

Tested in simulator with an IAM that shows on app certain versions.

Additional scenarios:

• tested every time conditions are satisfied
• tested with trigger

Testing

• [x] I have included test coverage for these changes, or explained why they are not needed
  • Only removing code. No existing coverage.
