```pycon
>>> from datasette.app import Datasette
>>> ds = Datasette(memory=True, files=[], sqlite_extensions=[""spatialite""])
>>> db = ds.add_memory_database('geo')
>>> await db.execute_write(""select InitSpatialMetadata(1)"")
UUID('3f143baa-4e3d-5842-a36f-4fa2f683b72f')
no such function: InitSpatialMetadata
```
It looks like the code that loads additional modules only works on read-only connections, not on write connections:

This could use the `find_spatialite()` function and, if it finds something, suggest the user use `--load-extension=spatialite`
