/* Test inclusion of previous build ID in telemetry pings when build ID changes.
*
* Cases to cover:
* 1) Run with no "previousBuildID" stored in prefs:
* -> no previousBuildID in telemetry system info, new value set in prefs.
* 2) previousBuildID in prefs, equal to current build ID:
* -> no previousBuildID in telemetry, prefs not updated.
* 3) previousBuildID in prefs, not equal to current build ID:
* -> previousBuildID in telemetry, new value set in prefs.
