add alias to subquery in doCalcRowCount()

[garak]

Without such alias, I get this error: "SQLSTATE[42000]: Syntax error or access violation: 1248 Every derived table must have its own alias"

Hey Massimiliano, thank you for your contribution.
Can you submit the PR to the new repo https://github.com/portphp/dbal-adapter?

[garak]

Of course I can, but what about this repo?
I'm using this in some projects of mine and I'd love to see this PR merged.
Is this repo still supported? Is there a migration path from this to portphp?

[Baachi]

We just moved the repo to an organization, but kept this repo to don't break any project.
So the new repo is the same as this, but with an new name.

@Baachi it looks to me that this is not "just moved". I mean, where is the new "data-import"? Also, I can't find any info in this repo's README about moving, nor I can find docs on the new one.
