ValueSet $expand is setting "total" to "count"

[plynchnlm]

Describe the bug
An expansion of the UCUM example ValueSet (and probably others) returns the expansion with the "total" field set to the requested "count" parameter, instead of the number of available results.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://hapi.fhir.org/baseR4/ValueSet/$expand?url=http%3A%2F%2Fhl7.org%2Ffhir%2FValueSet%2Fucum-common&filter=b&_format=application%2Fjson&count=7

Notice that "total" in the expansion (at the bottom) is set to "7", which is the count number.

2. Remove the count parameter from the URL, and notice that the "total" is now "101".

Expected behavior
The "total" parameter is supposed to be the number of available results. It lets you know whether you can request more results than what was returned. (If it were just the number of returned results, you could easily count those yourself.)
