tests: handle deleted .hg directory (git 2.2.0 and higher) (issue4585) In git 2.2.0 and higher, removing files and directories is changed: removing an object that does not exist returns success rather than failure. As a result, even though .hg/hgrc does not exist, success is returned and the .hg/ directory is removed. To handle this correctly, use 'rm -rf' to allow successful removing for all git versions. The exact changeset where this was introduced in git: 1054af7d04aef64378d69a0496b45cdbf6a0bef2 wrapper.c: remove/unlink_or_warn: simplify, treat ENOENT as success
