The 2nd query returns all records instead of the rest of them.

1. Create a table with hash and range keys.
2. Put there the items (for example, 10 ones) with the same hash key value (e.g., 'H') and range key values starting with the same sub-string (e.g., 'R').
3. Send query with key conditions specifying that hash key should be equal to 'H' and range key should begin with 'R'
    and limit equal to 2 (i.e. not all ten records are expected to be returned).
4. Send the second query with exclusive start key equal to LastEvaluatedTableName parameter value from the response to the first query.

Expected result: response to the second query contains the remaining 8 records.
Actual result: the response returns all queries including those two that were returned by the first response.
