  dosing regime dose groups hotfix
  We had a reported data corruption issue where a user edited content in a dosing regime and then after saving, we found multiple endpoint-groups with the same endpoint group id, which shouldn't be possible.
  
  After investigation, we found it was an error in the signal which keeps dose-groups and endpoint-groups synced. If there were multiple representation of dose-groups, for example 5 dose-groups and 2 units, then hawc would create 10 endpoint-groups instead of 5. Further, it would create these even for endpoints where data is not extracted.
  
  Here we fix this issue and write a few tests.
