Merge branch 'ambiguous-sha' into 'master'fondev

Fix ambiguous sha problem with mentioned commit

Before: write in database only 6 chars of commit sha. This cause to `Ambiguous SHA1 prefix` exception.

- [x] write full commit sha in db.
- [x] Standardise usage of sha truncation: 8 characters everywhere.
- [x] prevent exception when ambiguous sha requested in markdown

Fixes #1644
