[1.2.0]multiple function with mathematical operator return different line

[kauchy]

Bug report

System info: [1.2.0, CentOS 7]

Steps to reproduce:

1. Insert the following data

test value=1 1488252141000000000
test value=2 1488252151000000000
test value=3 1488252161000000000

2. Call max(),min() function with multiply

SELECT max("value")*1000,min("value")*1000 from test where time>1488252131s

Expected behavior:

time                max  min 
----                ---  ---
1488252131000000000 3000 1000

Actual behavior:

time                max  min 
----                ---  ---
1488252141000000000      1000
1488252161000000000 3000    

Additional info:

if delete the multiply operator,the result is what I expected

SELECT max("value"),min("value") from test where time>1488252131s

time                max min 
----                --- ---
1488252131000000000 3   1 

and in old version(v0.11.0),the result is always return 1 line with start query time.

It looks like it somehow got tricked into thinking that you had two selectors and didn't normalize the time for each one. I'll take a look at it.

Closing this in favor of #8167.
