Bug 1048525 - Use SuggestClient from MC.

Yeah, this patch handles the rename. It's not terribly clear, but if you look at the files changed (https://github.com/mozilla/fennec-search/pull/54/files), then this line indicates a rename:

/mozilla/search/autocomplete/SuggestClient.java → ...in/java/org/mozilla/gecko/home/SuggestClient.java
