 Functions like get_the_title() include isset() or !empty() checks on post
 object variables, but get_the_excerpt() is missing any such check. This
 missing check triggers PHP warnings if post_excerpt is not set.

 has_excerpt() addresses this for template usage, but nothing addresses
 this inside get_the_excerpt() itself.

 Attached patch adds an isset() check, and correctly passes an empty string
 if it doesn't.

 (Possibly of note: other convenience functions have this same issue --
 get_the_guid(), get_the_ID(), etc...)
