[RUN ALL RSPEC] Fix application settings helpers not being loaded in FOSS
In #324279 (closed), we saw a
failure only in the FOSS build because EE includes the
ApplicationSettingsHelper
in the EE routing helper but FOSS does not.
Since the loading of this helper isn't really EE-specific, we ensure all the includes are done in both EE and FOSS. This should eliminate subtle differences between CE and EE code.
Relates to #324279 (closed)
