Updating the expectation of TestUnsupportedInsertFormats test.

Previously it was expecting that inserting in any combination of text/codec where
codec!=none would fail. With the read compressed text patch, such an insert will
succeed by inserting uncompressed text, ignoring the compression type. This is a
temporary fix for this (code coverage) test to succeed, until the text writers are
in.

Partitioned hash join.

This is the first patch for partition hash join with spilling. End to end
inner join should be working but this new join operator is disabled by default.
