Default GeologicTimePeriod records are not linear between startPeriod and endPeriod

[grantfitzsimmons]

Describe the bug
The IUGS ICC chart is linear in moving towards the modern day, but our Chronostrat data switches if the larger number is the start period or the end period.

In short– the startPeriod value should be larger than the endPeriod value (million year increments), but that is not always the case currently.

To Reproduce
Steps to reproduce the behavior:

1. Create a database/discipline with a default Chronostratigraphy tree (takes place automatically if you create a discipline that is either invertpaleo or vertpaleo)
2. Query Chronostrat Name, Start Period, and End Period
3. See that startPeriod is not always larger than endPeriod, but sometimes is!

Expected behavior

• Our new default tree needs to be consistent in the order between startPeriod and endPeriod.
• Users with existing trees must not experience a crash when using new tools dependent on these ranges like the EAQ (Filter chrono names in the extended age filter  #5410)
• We should consider migrating these values to be in the appropriate order if the user has not modified the defaults in any way.
