[2.2.x] Fixed #30542 -- Fixed crash of numerical aggregations with filter.
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.
Thanks to Chuan-Zheng Lee for the report.
Regression in c690afb873cac8035a3cb3be7c597a5ff0e4b261 and two following
commits.
Backport of 4b6dfe16226a81fea464ac5f77942f4d6ba266e8 from master.
