This is a follow-up to incomplete fix in bug 1382649. In that bug, I attempted to
set the process count value to the e10s rollout value, when the user unchecks
"Use default performance settings". The same function updatePerformanceSettingsBox()
is actually run during page load, resulting the user set value being changed to
e10s rollout value if the user decided to use the default process count.
Tests are written for both patches.

When the user sets browser.preferences.defaultPerformanceSettings.enabled to false and want to set custom process count,
we want to offer the process count value given by e10s rollout add-on as the default, instead of the default value
of dom.ipc.processCount.
