I have a suggestion here: Tests will be easier to write if this method takes
indices of profiles that need to be compared. We currently do this in
live_bookmarks_sync_test.h by providing tests with a few options for
end-of-test-case checks. This scales to single, two, multi and many client
tests. For example, we can have:

bool HasSameExtensions(int profile_a, int profile_b);
bool HasSameExtensionsAsVerifier(int profile);
bool AllProfilesHaveSameExtensions();
bool AllProfilesHaveSameExtensionsAsVerifier();

Then, test cases that use the verifier can simply call
AllProfilesHaveSameExtensions(), while tests that make racy changes (and
therefore, do not use the verifier) can call
AllProfilesHaveSameExtensionsAsVerifier().

Done, although I added the functions I actually use. (I'll add the other ones
when I need them.)
