Default environment selection in search page settings

Solr settings cannot be exportable with features if the environments used in search pages are different in development server and production server, because in hook_apachesolr_search_default_searchers the env_id component of each search page does not accept a default value to get it from the variable apachesolr_default_environment.

I have two solr environments exported with features, Production (working on my production server) and Development (to use in my local development server). To have 'production' as the 'env_id' of my web search page forces me to manually change it after reverting features in my development server.
