[JGIT PATCH 2/2] ObjectId: Convert StringIndexOutOfBounds to IllegalArgumentException

If parsing an ObjectId fromString fails because the string is too short
we don't want to throw StringIndexOutOfBoundsException with a trace that
leads back to the error handling code; instead we should throw what the
caller expects us to throw, which is IllegalArgumentException.
