[devtools] CubicWebTC._check_html may have to deal with unicode or bytes If called with template=None, CubicWebTC.view will not go through main-template, and return the unicode data from the view directly instead of encoded data.

for table, column in [
        ('transactions', 'tx_time'),
        ('tx_entity_actions', 'tx_uuid'),
        ('tx_relation_actions', 'tx_uuid')]:
    repo.system_source.create_index(session, table, column)
