Azat Khuzhin 0365bc56aa Add backward compatiblity check for some functions
* State of aggregate functions

This test goes though all aggregate functions that:
- has only one argument
- support string as an argument

And do a simple check by creating the aggregate state with one string.

Yes this is not covers everything (does not cover functions with
different number of arguments, types, different states in case of
multiple values - uniqCombined, but as for uniqCombined it will be
checked via uniqHLL12), but at least something.

And about type, String had been selected, since it more likely that
there will be used some hash function internally.

* Function(String)

Check every function which has only one argument, and it's type is
String.
