V2 API next link doesn't contain SemVerLevel

[matthid]

While analyzing #5431 we also noticed that the next link from a request doesn't contain the required parameters which could lead to problems in pagination.

Example:
Request https://www.nuget.org/api/v2/FindPackagesById()?semVerLevel=2.0.0&id='NLog'
Response:
request_semver.xml.txt
<link rel="next" href="https://www.nuget.org/api/v2/FindPackagesById()?id=%27NLog%27&amp;$skip=100" /> <- Missing semVerLevel=2.0.0

Response Headers:
request_semver.txt
