sql: xfer optimization issue

Currently insertion from the table to another one
with the same schema using SELECT works wrong.
The problem lies in xfer optimization which opens cursors for
all of the indexes and inserts data excessively.
Now only PRIMARY KEY is used to handle insertion.
Moreover obsolete check from sqlite3 were used,
accordingly this optimization was improved in accordance
with the actual Tarantool internals.

Closes #3307
