Please describe the problem:
Deskbar does not take note when I switch the default browser, it continues to use the old search settings.

Steps to reproduce:
1. Verify that web search is enabled
2. switch your preferred browser, e.g. from epiphany to firefox or vice-versa
3. try to do a web search with deskbar


Actual results:
Old settings, in this case epihphany's intelligent bookmarks are used for performing the search

Expected results:
Deskbar should use firefox' search plugins, now that it has become the default browser

Does this happen every time?
yup.
