Do not require identical values when searching for a main value
E.g. a value obtained using WQ.getRawValue() is not necessarily
numerically identical, but nevertheless to be considered equal,
to a matching Q main value.
Fixes wrong descriptions in the result of a water level calculation,
where not finding a matching main value led to the value being used
as description instead of the name of the matching main value.
