Issue ID: ANLY-3975

Details: When the ta.pull function has a table name argument, it fetches NULL values incorrectly. For example:
ta.pull("empty_values_tab") -> r1
> r1
val_1 val_2 val_3
3 a c
11 
4 a b 
1 a b c
5 
2 b c
Workaround: Create a virtual data frame and use it instead of the table name in the ta.pull call. For example:
ta.data.frame("select * from empty_values_tab",sourceType="query")-> vdf
> ta.pull(vdf)-> r2
> r2val_1 val_2 val_3
3 a c
11 <NA> <NA> <NA>
2 b c
4 a b 
1 a b c
