Simon Charette 9dee8515d6 [2.2.x] Fixed #30628 -- Adjusted expression identity to differentiate bound fields. 
Expressions referring to different bound fields should not be
considered equal.

Thanks Julien Enselme for the detailed report.

Fixed hanging indentation in various code. 2018-03-16 10:54:34 +01:00
Simon Charette 277ed07209 Fixed #29195 -- Fixed Exists.output_field resolution on single-valued queries. 
The Subquery class which Exists inherits from defaulted to using single-valued
querie's field if no output_field was explicitly specified on initialization
which was bypassing the Exists.output_field defined at the class level.

Moving Subquery's dynamic output_field resolution to _resolve_output_field
should make sure the fallback logic is only performed if required.

Regression in 08654a99bb.

Thanks Oli Warner for the detailed report.
