Ensure semester and settings models initializer should not run on setup

[kwfk]

ensure_semester_and_settings_present initializer should not run on setup.
This breaks rake db:setup and even rake db:create because rails runs all initializer and this initializer causes a db does not exist error before database can be created.
Currently able to be resolved by commenting out the initializer then uncommenting it after running rake db:setup

After running rake db:setup without uncommenting:

rake aborted!
