bc7e288ca9 Fixed #29745 -- Based Expression equality on detailed initialization signature. 
The old implementation considered objects initialized with an equivalent
signature different if some arguments were provided positionally instead of
as keyword arguments.

Refs #11964, #26167.

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 08654a99bbdd09049d682ae57cc94241534b29f0.

Thanks Oli Warner for the detailed report.

08654a99bb Fixed #28492 -- Defined default output_field of expressions at the class level. 
This wasn't possible when settings were accessed during Field initialization
time as our test suite setup script was triggering imports of expressions
before settings were configured.

6e4c6281db Reverted "Fixed #27818 -- Replaced try/except/pass with contextlib.suppress()." 
This reverts commit 550cb3a365dee4edfdd1563224d5304de2a57fda
