stuff separated by comma(s) inside parenthesis generate extra columns with empty title

First trouble with 1.5.0 : #9562
To reproduce bug see below

[lipoteFR]

#!/bin/env python
from influxdb import InfluxDBClient
client = InfluxDBClient( host='<ip>', port=8086 )

client.drop_measurement('test_bug')
p = [{ "measurement" : "test_bug"
     , "time"        : "2018-03-14T09:00:00Z"
     , "tags"        : {"tag_key": "tag_value"}
     , "fields"      : { "value": 0.64} } ]

client.write_points(p)

result = client.query("SELECT * FROM test_bug")
print result
#exit(8)
p = [{ "measurement" : "test_bug"
     , "time"        : "2018-03-14T08:00:00Z"
     , "tags"        : {"tag_key": "tag_value (toto, titi)"}
     , "fields"      : { "value": 0.64} } ]

client.write_points(p)

result = client.query("SELECT * FROM test_bug")
print result

gives :

ResultSet({'(u'test_bug', None)': 
[{u'tag_key': u'tag_value', u'value': 0.64, u'time': u'2018-03-14T09:00:00Z'}]})

ResultSet({'(u'test_bug', None)': 
[{u'': None, u'tag_key': u'tag_value (toto, titi)', u'value': 0.64, u'time': u'2018-03-14T08:00:00Z'}
,{u'': None, u'tag_key': u'tag_value', u'value': 0.64, u'time': u'2018-03-14T09:00:00Z'}]})

Because tag_value contains (toto,tutu) a new column appear
it brakes every thing
We test also with just (,) same bug
Ma base est toute cassée (crote)

Thanks for these repro steps. I can now repro the issue. I'm going to close this issue as it's a duplicate of #9545. I'll update with status there.
