Abort running validation tests

[dcarter]

Test: arm4test_register_application terminate called after throwing an instance of 'DbException?'

what(): Db::set_flags: Invalid argument

This is caused by calling the OpenDatabasesReadOnly? method. Removing the read only flag allows it to work fine.

Possibly the databases have already been opened with other flags?

As a workaround, the ReadOnly? version can be identical to the non-read only version.
