Fix evaluation of SQLite driver options

Ensure that the options, which are passed to the SQLite driver, are
evaluated in the correct order and do not overwrite each other.

SQLITE_OPEN_READONLY and (SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE) are
mutual exclusive, but SQLITE_OPEN_URI can be combined with both of them.
