refactor: remove `submission_email` column from `teams` table

[RODO94]

What does this PR do?

To finish the work on https://trello.com/c/dVsTQpZZ/2984-allow-editors-to-see-update-their-teams-submission-email-in-team-settings-form

I have dropped the redundant column and adjusted the scripts which create the local DBs.

In order to keep the team_summary table, I had to adjust the sql code which creates it. From here I also repointed the homepage column of this table from teams table to team_settings table.

Up script running order:

1. Change team_summary view using team_settings.submission_email column
2. Remove teams.submission_email column

Down script:

1. Add teams.submission_email column
2. Replace team_summary view using new column

Regression tests passing
