Get deletion of networks in controller going

Multiple statements in a sqlite3_prepare_v2 is not usable. Only
the first statement will be executed.

Since the schema now uses 'ON DELETE CASCADE', there's only
one statement needed.

If multiple statements are needed, there should be either multiple
sqlite3_prepare_v2 calls be used or the sqlite3_exec function.
