MySQL error in ORDER BY clause in get_artefactchooser_artefacts()

For some reason works fine on Postgres...

To reproduce:

1. Create a journal post.
2. Go to pages.
3. Create a page.
4. Add "Journal entry" block.
5. See this error:

Failed to get a recordset: mysqli error: [1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'BY parent ASC, ctime DESC LIMIT 10' at line 15] in EXECUTE("SELECT a.*, (a.owner IS NOT NULL AND a.owner = '1') AS editable FROM "mhr_artefact" a WHERE ( a.owner = '1' OR a.id IN ( SELECT id FROM "mhr_artefact" WHERE (path = '/5' OR path LIKE '/5/%') AND institution = 'mahara' ) OR a.id IN ( SELECT aar.artefact FROM "mhr_group_member" m JOIN "mhr_artefact" aa ON m.group = aa.group JOIN "mhr_artefact_access_role" aar ON aar.role = m.role AND aar.artefact = aa.id WHERE m.member = '1' AND aar.can_republish = 1 ) OR a.id IN (SELECT artefact FROM "mhr_artefact_access_usr" WHERE usr = '1' AND can_republish = 1) OR a.institution IN ('mahara') ) AND artefacttype IN('blogpost') AND id = 6ORDER BY parent ASC, ctime DESC LIMIT 10") Command was: SELECT a.*, (a.owner IS NOT NULL AND a.owner = ?)

AND id = 6ORDER BY parent ASC, ctime DESC and values was (1,1,/5,/5/%,1,1,mahara,blogpost)

SQL is missing space before ORDER BY...
