Bugfix: Use `--cache-dir` argument for `check` command
`check` command now uses a temporary sub-directory of the specified directory
if set using the `--cache-dir` argument. If not set, the cache directory is
created in the default temporary directory as before.
In either case a temporary cache is used to ensure the actual repository is
checked (rather than a local copy).
The `--cache-dir` argument was not used by the `check` command, instead a
cache directory was created in the temporary directory.
