Fix `WebFluxAutoConfigurationTests` following upstream Spring Framework
changes. Also refine `WebMvcAutoConfigurationTests` to check the locations
are set even if they are filtered.
See gh-28223
Spring Framework will filter non-existent locations from any configured
static resource handlers starting with 5.3.11. Tests that verify
static resource locations should account for this change.

Previously, the detector for AbstractDataSourceInitializers used the
default detector order. This resulted in the initializers detected
initializers running before Flyway. Constrastingly, the detector for
DataSourceScriptDatabaseInitializers uses a custom order so its
detected initializers would run after Flyway.
This commit aligns the order of the detector for
AbstractDataSourceInitializers with the order of the detector for
DataSourceScriptDatabaseInitializers. This ensures that script-based
initialization runs in the same order with respect to Flyway,
irrespective of which initializer implementation is driving it.
Fixes gh-28079
Previously, when the preferred json mapper was set to Gson, the Gson
HTTP message converter was added before any other converters. This
changed the form of String responses that were already valid. When
Jackson is in use, a string converter is used as it appears earlier
in the list than the Jackson converter. When the mapper is switched
to Gson, the Gson converter is added first in the list of converters
and the Strong converter is no longer used. This results in the
String, that was already valid JSON, being converted again. This
changes its form as quotes are escaped, etc.
This commit updates HttpMessageConverters so that the Gson converter
is added to the list immediately before the default Jackson
converter. This is done by considering the Gson converter to be an
equivalent of the Jackson converter.
