Filtering nested properties with a name converter won't work reliably

[bendavies]

Introduced in:
#2751

Example:

With CamelCaseToSnakeCaseNameConverter configured

Specify a filter such as:

 * @ApiFilter(SearchFilter::class, properties={"customer.fooBar": "exact"})

a client should be able to request:

GET /resource/?customer.foo_bar=baz

but the property being filtered will be converted to customer_FooBar in AbstractContextAwareFilter, so will obviously fail to filter the nested property correctly.
