layouts: fix crash when importing hgext_hgsubversion This change was introduced in 4a92eb1484ba and fixed importing issues for mercurial < 2.8. Unfortunately, this broke imports for newer versions of mercurial that have hgsubversion installed in sys.path. We now wrap the import in a try-block to catch this ImportError.
