sqlite: fixes from sytest (#872)
* bugfix: fix panic on new invite events from sytest I'm unsure why the previous code didn't work, but it's clearer, quicker and easier to read the `LastInsertID()` way. Previously, the code would panic as the SELECT would fail to find the last inserted row ID. * sqlite: Fix UNIQUE violations and close more cursors - Add missing `defer rows.Close()` - Do not have the state block NID as a PRIMARY KEY else it breaks for blocks with >1 state event in them. Instead, rejig the queries so we can still have monotonically increasing integers without using AUTOINCREMENT (which mandates PRIMARY KEY). * sqlite: Add missing variadic function * Use LastInsertId because empirically it works over the SELECT form (though I don't know why that is) * sqlite: Fix invite table by using the global stream pos rather than one specific to invites If we don't use the global, clients don't get notified about any invites because the position is too low. * linting: shadowing * sqlite: do not use last rowid, we already know the stream pos! * sqlite: Fix account data table in syncapi by commiting insert txns! * sqlite: Fix failing federation invite Was failing with 'database is locked' due to multiple write txns being taken out. * sqlite: Ensure we return exactly the number of events found in the database Previously we would return exactly the number of *requested* events, which meant that several zero-initialised events would bubble through the system, failing at JSON serialisation time. * sqlite: let's just ignore the problem for now.... * linting
