Calling prepare and execute did not update corresponding request statistics
in the box.stat table. This happened because methods that collect stats were
never called where they should have been.

There was a bug in previous commit resulting in collecting statistics on
box.execute twice in some cases.

 

Closes #4756

Calling prepare and execute did not update corresponding request statistics
in the box.stat table. This happened because methods that collect stats were
never called where they should have been.

 

Version for 2.2 only includes box.execute.
