[NuGet.org Bug]: Embedded license endpoint returns 500 when package is deleted

[joelverhagen]

Impact

It bothers me. A fix would be nice

Describe the bug

If a package had an embedded license file but is deleted, the /packages/{id}/{version}/license endpoint returns HTTP 500.

Example:
/packages/SocialMediaSharing/5.1.1/license

Error:

Repro Steps

https://www.nuget.org/packages/SocialMediaSharing/5.1.1/license

Expected Behavior

This should show that the package is delete, not return HTTP 500.
