Removes double request when viewing detail view directly

When visiting an entry directly two requests were being made. This
commit makes it so only one request is performed in this case.

Fixes error in detail view when no parameters are present

When a view is accessed directly and no parameters are present the view
was throwing an error because the organization was not necessarily
found in the search results because only the first 30 results are
returned. This commit performs a second query for the specific
organization if the first query didn't include it.

Adds nil? check for location searches

For location searches, the orgs property is nil, so this adds a check
for that in the organization controller.
Fixes no results map issue

When map had no results it was trying to fit to the bounds of the
markers. Since there aren't any when there are no results, the map was
throwing a JavaScript error. This fixes the issue by first checking
that markers exist before performing a fit to bounds operation on the
map.
