Subject: [PATCH] Fix snippets for non-ICU / seqno not updated

seqno was not updated in snippet_add_complete_field in the same way
as extract_add_complete_field. This would make snippet maching incorrect
and match incorrect snippet tokens. Problem introduced in commit
13551199cc4f367c3699fd079d3f7021075a6059.
