Nuget Virtual repository not resolving artifacts beyond the first 80 versions (by default)

Problem Statement:
In Artifactory version 6.19 - the NuGet virtual repository is not looking for artifact versions beyond the first 80 entries until a version beyond 80 entries is specified.

Impact:
The existing builds of the customers using Nuget virtual repositories will fail automatically due to this.

Steps to reproduce:

• Use Artifactory v6.19
• Follow set me up steps for resolving package FluentAssertions from remote repository and similarly from Virtual repository - notice the difference in the version of package donwloaded.

Actual results:
Downloaded version from remote and virtual repositories is different for the same package.

Expected results:
Downloaded version from remote and virtual repositories should be same.

On debugging further, I found the issue is happening due to first 80 entries only being looked for from Virtual repositories, i.e. in Artifactory 6.12.x:

v/s Artifactory 6.19:

  OK http://mill.jfrog.info:12510/artifactory/api/nuget/nuget/Download/FluentAssertions/5.3.0 2821ms

Workaround:
Use a remote repository instead/specify version while downloading from Virtual
