Enable SearchEngineTabHelper to add new TemplateURL to TemplateURLService
by following steps:
    1. When a searchable URL is generated from <form> submission, save
       it to SearchEngineTabHelper;
    2. If the navigation caused by <form> successfully finishes, create a
       new TemplateURL by recorded searchable URL and add it to
       TemplateURLService, then erase the recorded url. Failed navigation
       will be ignored because in that condition the generated searchable
       URL will probably lead user into an error page;
