Remove call to nonexistent endpoint

[d-j-hatton]

Fixes bug introduced in #863. Currently it tries to do a database update through an endpoint that doesn't exist but as it is part of the API it should just do the update itself.

This function is repeated in almost every module where SmartEM is used. I wonder if it's worth breaking it out into a helper function in a module in murfey.util or smartem_backend.

The logic for loading the SmartEM KeyCloak client seems pretty repetitive, so I wonder if it's worth breaking it out into a helper function in a module in murfey.util or smartem_backend.

Other than that, I couldn't spot any noticeable issues!
