reintroduced inputfile.seek(0) to utils.uncompress_file

[truePhilipp]

Description

This is a very small fix for #292.
I think this issue got introduced way back by #189.
In there line 244 inputfile.seek(0) got removed, which seems to cause this issue.
Simply reintroducing this line makes the uncompressing work again.

Can you add a line item on the changelog, and a unit test (if feasible)?

[truePhilipp]

@Archmonger yes, sure. The changelog is docs/changelog.rst right? The newest main point is 4.0.0b0 (2021-12-19) should I just add it there?

[Archmonger]

This change would belong in an Unreleased section until a formal release is made.

On a side note, looks like there was a bit of forgetfulness of bumping the changelog from @johnthagen and I.

I will retroactively add v4.0.2 and v4.1.0 to the changelog in a separate PR.

Changelog PR has been created: #504

[truePhilipp]

Ok, i added a test and the edited the changelog.
I have noticed that the test DbRestoreCommandTest.test_compressed does not actually check if the restore succeeded…
I don‘t know where to report that, so i‘ll just do it here. It could be fixed by adding two lines, should I do that in this merge request as well, or should i open another one for that, since it has nothing to do with this?

[Archmonger]

That's pretty minor so feel free to fold it into this PR.
