Anssi Kääriäinen 8ef3235034 Fixed #19720 -- Oracle ordering related delete regression 
When a query had a complex where condition (a condition targeting more
than the base table) a subquery was used for deletion. However, the
query had default ordering from the model's meta and Oracle doesn't
work with ordered subqueries.

The regression was caused by fast-path deletion code introduced in
1cd6e04cd4 for fixing #18676.

Thanks to Dylan Klomparens for the report.

Anssi Kääriäinen f64a5ef404 Fixed #19102 -- Fixed fast-path delete for modified SELECT clause cases 
There was a bug introduced in #18676 which caused fast-path deletes
implemented as "DELETE WHERE pk IN <subquery>" to fail if the SELECT
clause contained additional stuff (for example extra() and annotate()).

Thanks to Trac alias pressureman for spotting this regression.

Alex Gaynor d362c1546f Convert much of the regression tests to use absolute imports. There's still work to be done though.

Karen Tracey 4e4decaf42 Tweaked a test model in delete_regress to avoid having a column name that causes a failure on Oracle.
