GET /search ignores intersects parameter

GET /search ignores the `intersects` parameter

e.g.,

```
http://localhost:8082/search?intersects={%27type%27:%20%27Polygon%27,%20%27coordinates%27:%20[[[100.0,%200.0],%20[101.0,%200.0],%20[101.0,%201.0],%20[100.0,%201.0],%20[100.0,%200.0]]]}
```

returns Items that are not in the polygon. This behavior is visible on the Planetary Computer.

POST with an intersects field works.
