Karthik Nayak 351c6e719a refs/ref-cache: fix SEGFAULT when seeking in empty directories 
The 'cache_ref_iterator_seek()' function is used to seek the
`ref_iterator` to the desired reference in the ref-cache mechanism. We
use the seeking functionality to implement the '--start-after' flag in
'git-for-each-ref(1)'.

When using the files-backend with packed-refs, it is possible that some
of the refs directories are empty. For e.g. just after repacking, the
'refs/heads' directory would be empty. The ref-cache seek mechanism,
doesn't take this into consideration when descending into a
subdirectory, and makes an out of bounds access, causing SEGFAULT as we
try to access entries within the directory. Fix this by breaking out of
the loop when we enter an empty directory.

Since we start with the base directory of 'refs/' which is never empty,
it is okay to perform this check after the first iteration in the
`do..while` clause.

Add tests which simulate this behavior and also provide coverage over
using the feature over packed-refs.
