Adapt test to new behaviour

Now an error occurs before craeeteLayergroup when checking affected
tables for overviews information. This prevents the creation of the
map configuration, so the corresponding redis keys need not be deleted.

The error message changes also because now the error originates in
a different function call, QueryTablesApi.prototype.getAffectedTablesInQuery
vs getAffectedTablesAndLastUpdatedTime.
