sync/import issue

[janul]

Due to default mysql collation the search is case insensitive
this cause the issue if:

• in imported/synced metadata there is entityID="XYZ"
• there is entityID="xyz" in jagger already
  So by the search both entities are the same entity but during internal veryfication (strict comparison) there are not and it causes Doctrine exception during sync with db.

for now just added error log if such issue occurs commit: 0ca9d7b
