Bug description:
Error:
[WAR] 75 (lib/dml.php:514) Failed to get a recordset: mysqli error: [1146:
Table 'mahara_new.artefact_file_embedded' doesn't exist] in EXECUTE("SELECT

"resourcetype" = 'blogpost' AND "resourceid" = '11534' ")

"resourceid" = ? and values was (0:11498,1:blogpost,2:11534)

The reason is that the artefact.blog upgrade for version 2015011501
assumes that the artefact.file upgrade for 2015111200 has already
taken place and, hence, that the table 'artefact_file_embedded' has
been created.
This is not the case for an upgrade from 1.9.7 to 16.04.4.
To work around this I've forced artefact.file to be the first artefact
to be upgraded, by adding the following code to 'sort_upgrades':
if ($weight1 == $weight2) {
if ($k1 == 'artefact.file') {
return -1;
} else if ($k2 == 'artefact.file') {
return 1;
}
}
This is a temporary change to make sure that the upgrade can be
completed (which it has now done), but reporting here in the hope that
this will save anyone else having similar problems.
