Comment (by lrntct):

 Dropping the table with the command line tool works correctly:
 {{{
 /usr/lib/grass72/scripts/db.droptable -f table=drainage_network_junction
 Forcing ...
 (Wed Nov 16 15:29:15 2016) Command finished (4 sec)
 }}}

 Below is a minimum working example:

 {{{
 from grass.pygrass.vector import VectorTopo
 from grass.pygrass.vector.table import Link

 cols = [(u'cat', 'INTEGER PRIMARY KEY'),
         (u'name', 'TEXT')]

 cols_j = [(u'cat', 'INTEGER PRIMARY KEY'),
           (u'junction', 'TEXT')]

 with VectorTopo('drop_table_test', mode='w', tab_cols=cols) as vect_map:
     l_junc = Link(layer=1, name='link_name',
                   table=vect_map.name + 'junc', key='cat')
     t_junc = l_junc.table()
     t_junc.create(cols_j, overwrite=True)
 }}}

 Just run two times the script to see the error.
