[JGIT PATCH] BlobBasedConfig now does not print stacktrace to stderr if blob is not found by path

[Constantine Plotnikov <constantine.plotnikov@gmail.com>]

Prior to this patch, if the blob is not found inside commit by path,
an exception stack trace was printed to stderr. This patch suppress
this behavior by throwing FileNotFoundException instead of generic
IOException in order to make it more aligned with FileBasedConfig.
