Add acceptance for test for sync.paths equal to two dots (#2196)

Based on integration test from @andrewnester in #2194

Manually checked that this databricks.yml passes validation on v0.235.0
but fails on v0.236.0, very like it was broken in
#1945

This also adds replacements for tmpdir, it's parent and (just in case)
grand parent.
