fix a node-sqlite3-ism that breaks record removal in grist-static (#566)

Grist by default uses node-sqlite3 to manipulate data in an
SQLite database. If a single parameter is passed to `run`
and it is a list, the list is unpacked and its contents treated
as the actual parameters. In grist-static, we use other SQLite
interfaces that don't have that automatic unpacking. Most
calls like this have been removed from Grist, but at least one
was missed, and was causing symptoms such as
https://github.com/gristlabs/grist-static/issues/5

This change should make no difference to regular Grist, but
resolves the grist-static problems.
