Vector info bug

[anikaweinmann]

If a vector has no database connection because it has no tabel, actinia returns an error by requesting the information of the vector map:

# test_random_vect created with e.g. grass grassdb/nc_spm_08/PERMANENT/ --exec v.random output=test_random_vect npoints=10

curl -u ${AUTH} ${URL}/locations/nc_spm_08/mapsets/PERMANENT/vector_layers/test_random_vect | jq

}

The endpoint should not return an error if no table is set for the vector map.
