Title: Fix a lovely little error scenario which occurs when it can find no previous releases.

A. It tries to get_release(-1), which returns undef , and then it tries
undef->version() , which can't work.

B. When you avoid the former by checking for an empty release set first,
it dies trying to dereference "undef" to an array to return
elements(), so pre-populating the array with a default empty
array-reference is required for it to work.
