[test] use pytest tmpdir fixture in all tests

Tests that were imported from u1db or created on top of that structure
were leaving temporary directories behind. This could cause problems in
test servers, either by filling the partition or by extrapolating the
maximum amount of files in a directory.

This commit replaces all usages of temporary directories in the old test
structure by pytest tmpdir fixture, which properly cares for removing
temporary directories.
