bug-fix: use completeBaseName() when adding sequence to file name

- When adding attachments, if the name conflicts, we add sequence after
the base name. "abc.tar.gz" to "abc_001.tar.gz".
- When handling notes and folders, if the name conflicts, we add
sequence after the complete base name. "abc.5.9.1.md" to
"abc.5.9.1_001.md".
