fix(git-downloader): un-ignore test_remove via FilesystemMock path seam

The ignore reason went stale: the FilesystemMock seam added for
FileDownloaderTest already intercepts removeDirectoryAsync, and the
sibling fossil/hg testRemove ports use it. The seam now records the
removed directories instead of a bare call count so the PHP
->with($this->equalTo($this->workingDir)) argument assertion can be
reproduced faithfully.
