Fix early abort on files deletion loop

[speed47]

Closes #352
Closes #353

[speed47]

Currently being tested to ensure it does fix the problem as it should.

Let me know how it goes, I'll make a new release if you like

It works, all the files older than 30 days finally vanished from the FS :)

Note that a better version of the patch would probably handle "file not found" errors differently than other errors, as "file not found" would imply that the file might have been deleted manually, so we should just ignore the error and delete the row from the db.

For this, backends would need to return some specific well-known error (or return another flag appart from the error) so that it can be catched and handled properly.

It just means we have some dead rows, I can live with that in the meantime :)

no more travis builds :'(

Aww, yep :/ Hopefully migrating to GitHub Actions is not too painful starting from the workflow you had with travis

I ran tests locally and it seems fine, we might want add a test case though.
I'll try to take a look at GA tomorrow or Friday and to cut a 1.3.2 release with the last few patches.

Thanks for the patch :)
