notes: fix handling of colon-separated values

Browse Source 
The substrings output by strbuf_split() include the ':' delimiters.
When processing GIT_NOTES_DISPLAY_REF and GIT_NOTES_REWRITE_REF, strip
off the delimiter character *before* checking whether the substring is
empty rather than after, so that empty strings within the list are
also skipped.
