Fix Open() journal mode regression

[why]
see https://github.com/mattn/go-sqlite3/issues/607

SQLite default journal mode is DELETE, but forcing it on open causes "database is locked"
if other connection exists with WAL mode, for example.

[how]
Don't set DELETE mode if not set in DSN explicitly.

[testing]
Run tests in my project where WAL mode is used.
