What You Are Seeing?

When searching a NuGet v3 endpoints, the Chocolatey CLI query includes an empty query string q=.

What is Expected?

When there is no specific search, the query string should not be included at all. As defined in the NuGet Server API:

Name	In	Type	Required	Notes
q	URL	string	no	The search terms to used to filter packages

(emphasis mine)

How Did You Get This To Happen?

1. Add a NuGet v3 source to Chocolatey CLI.
2. 1. Setup Fiddler to intercept the queries that are made by Chocolatey CLI to the source.
3. Run a choco search --source <SOURCE SETUP ABOVE>.
4. Look at the Fiddler traffic to see the queries being made from Chocolatey CLI.

NOTE: This was discovered on a call with @gep13 while looking at #3502 so is from memory. We used Sleet, as per the #3502 issue and saw the queries that were made, within the Sleet interface itself. So we didn't use Fiddler but I am assuming Fiddler will also show you the queries.
