Log correct experiment assignments for horizontal mode experiments

[amk-stripe]

Summary

Log correct experiment assignments for horizontal mode experiments

Motivation

Currently experiment assignments for both A/A tests are logged as being for the Android-only A/A test. Updated the LoggableExperiment to take a param indicating which experiment we are logging an exposure for.

Testing

• Added tests
• Modified tests
• Manually verified

Added network tests
