Sander Steffann 06f76a2741 Fix IndexError when junos_config contains multiple delete lines (#25139) ... * Prevent IndexError when deleting multiple lines The old code will raise `IndexError: list assignment index out of range` when deleting multiple lines because the indexes of the original and the copy get out of sync. Solved by deleting from the high indexes first so the lower ones remain stable. * Don't load configuration if nothing to load Instead of sending an empty candidate config (for example because the candidate only consisted of `delete` lines, and all of them were filtered out by `filter_delete_statements`) just return. JunOS seems to get confused by empty changes, and if the candidate config is empty then it's a no-op anyway.		2017-05-30 11:55:25 +05:30
