Review comment:
Yeah... I found in my tests that these fail as well. Maybe comment them
with a jira number... Not important, though.

> PHOENIX-5629 introduced the function PHOENIX_ROW_TIMESTAMP() that returns the
> last modified time of a row. PHOENIX_ROW_TIMESTAMP() can be used as a
> projection column and referred in a WHERE clause. It is desirable to have
> indexes on row timestamps. This will result in fast time range queries.
