SqLite: Fix fatal error when resource closed prior to result destructing

[dakujem]

Bug fix; bc break: NO

I'm running into an issue in a certain setup with SqLite driver:

See, the resource has already been closed before the destruction of the result object.

Adding is_resource check is an efficient way to prevent it, possibly even the suppression operator @ on line 40 might become redundant after this change.

I'm guessing this is similar to #409.

[dakujem]

I forgot to add that this only happens with PHP 8 and above.

@dg bump.

is_resource($this->getResultResource()) this will always return false, that's probably not the right fix…

[dakujem]

I fail to understand the reason for rejecting this PR. If it did not happen I would not have been fixing it.
Why do you think is_resource($this->getResultResource()) will always evaluate to false?

[dakujem]

How is this different to #431?

[dg]

Because getResultResource() returns object.

[dakujem]

... and in 8e7df83 you completely removed the auto-free feature, which renders this PR as well as #431 irrelevant anyway.
