I had a look at this and found a copy-pasto in one of the test cases
while testing, patch attached.
I've also attached a second patch (that applies on top of the first)
that removes the base backups once they are no longer needed, also
attached (but see below).

They (and the base backups) are getting purged on success of the whole
testsuite. So to be clear - we are not leaving behind 1 GB of disk space
on success, but we use 1 GB of disk space during the test.

I used rmtree() from File::Path (which is also used by PostgresNode to
clean up) to remove them during the run.
