Merge 'CREATE VIRTUAL TABLE fixes' from Piotr Rżysko

Browse source 
This PR fixes two bugs in `CREATE VIRTUAL TABLE` (see individual commits
for details).
I added a test in `extensions.py` instead of the TCL test suite because
it's currently more convenient - there’s no existing framework for
loading extensions in TCL tests. However, I believe the test should
eventually be moved to TCL, as it verifies behavior expected to be
compatible with SQLite and is independent of any specific extension.
I've seen a PR proposing to migrate TCL tests to Rust, so please let me
know if moving this test to TCL would still be valuable.
