fix(webapi): unique username/email check on change user #1561
there is a global IRI lock. The point would be not to perform an update if the value hasn't changed. The issue is the scope of the conditions respectively the exceptions thrown in it. As in the code on develop, the exception is thrown but doesn't lead to not executing the rest of the function. As in this PR, everything works as intended, but there's no longer a check whether the new value is actually new.
