Keep track of all reimported date ranges in case reimported ranges fall outside initial range

[diosmosis]

If a user imports a range, then reimports dates outside of that range, there is a danger they may invalidate/re-archive those dates and lose GA data permanently.

The workflow for this bug would be:

• User imports, eg, 2020-07-01,2020-08-01
• User re-imports 2020-06-03,2020-06-04
• User later invalidates 2020-06-03 and re-archives
• This results in no data displaying for that day

This is due to GoogleAnalyticsImporter::isRequestAuthorizedToArchive() thinking, since the date is not within the main import date range, we can safely re-archive it.

To prevent we need to keep track of every re-imported date range as well the main one.

Note: this is an edge case.
