Steps to Reproduce

1. Use the REST api with a python to bulk add groups.
2. It shows status 200, but the user isn't really added.

Expected Results

Using endpoint /rest/api/3/group/user to add / remove users in bulk when having apostrophe in the group name should result in 404

Extra Note:
eg of language use is Python, when using a for loop and reading the data from a csv file to add / remove users in bulk such behaviour is noticeable

Actual Results

using /rest/api/3/group/user to add / remove users in bulk shows as 200 status code for Adding / removing users which is wrong.
e.g. groupname = Felix's

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
