Error in find_records_with_rbac when resetting tagging of an instance

Description of problem:
Reset button doesn't work for tag page for instances in Compute -> Clouds -> Instances -> Instances by Provider.

Version-Release number of selected component (if applicable):
5.9.

How reproducible:
100%

Steps to Reproduce:
1. Add some Cloud Provider (if there is no one)
2. Go to Compute -> Clouds -> Instances -> Instances by Provider tab
3. Check some instance(s) from the list of All Instances by Provider
   or go to the details page of some instance (click on it)
4. Under Policy, click on Edit Tags
5. Do some change in tags
6. Click on Reset button to reset the changes

Actual results:
Reset button does not work, nothing happens after clicking on it, just error occurs in log (in find_records_with_rbac, see the attachment). The same happens when trying to click on Reset button again.

Expected results:
Reset button should work, changes made in tag page should be reset, no error should occur.

Additional info:
After clicking on Cancel button to get out of tag page, we can see All Instances by Provider again. Also saving the changes works.
