explicitly set secure_delete pragma for SQLite database
Conversations stores sensitive data, such as SQLiteAxolotlStore tables, in its database. secure_delete=ON is the default for newer Android devices: https://android-review.googlesource.com/c/platform/external/sqlite/+/209123 However, older devices had it disabled by default, so any database created than has this setting disabled and it will not be updated automatically. Also, the default might be changed in the future (for example, to "FAST", added in 2017), so it is safer to set it explicitly.
