Minefield does not read extension defaults.

I checked about:config, extension defaults preferences are not available any more.

The testcase xpi add several default preferences like followings,
pref("[e-mail]", "READ DEFAULT PREFERENCES");
pref("extensions.defaultpreferences.bool", true);
pref("extensions.defaultpreferences.int", 0);
pref("extensions.defaultpreferences.str", "AAAAAAAAAAAAAAAA");

Reproducible: Always

Steps to Reproduce:
1. Start Latest hourly Minefield with new profile
2. Install testcase xpi and Restart browser.
3. Open about:config and filter with  "extensions.defaultpreferences" (without quotation)

Actual Results:
 threre are not available preferences of extensions.defaultpreferences.*

Expected Results:
